Still inspired by my latest patch, I decided to once again use four slow waves to control the levels of the Synthesis Technology E370, gently bringing them in and out of audibility. But rather than using Swell Physics to set the flow, I decided to use the flow of pure chaos. These sorts of soundscapes are amongst my favorite patches to create. They’re almost always exceedingly beautiful, and I’ve found that even similar patches can yield radically different results. I have a small library of slow motion patching techniques I use regularly, and I’m continuously looking for new ways of expanding upon them. Whether that be newly created control schemes, or simply making small adaptations to ones already in my toolbox, I’m constantly seeking new routes and trying to learn new methods.
The beating heart of this patch began with the Nonlinearcircuits Frisson, an eight output chaos module based on Mackey-Glass equations, with some help from its chaotic friends, Helvetica Scenario, Triple Sloth, and The Hypster, as well as assists from fellow NLC friends, Numberwang and Let’s Splosh. Frisson is a chaos module that gives some control, but not an overwhelming amount. You can control phasing of the outputs, which also increasingly have more slew, and the speed can be somewhat controlled, though not really. You can also CV control the phasing, or inject an external signal into the internal chaos. It also can be alternatively used as a CV phaser, taking an input, while phasing the outputs and increasingly adding slew. It’s a fantastic way of getting eight closely related modulation signals. I’ve used Frisson in the past, it was a goodly part of my last patch too, but this time I used it differently. Rather than being solely used for modulation of some secondary parameter like a filter cutoff, this time Frisson’s chaos was the star of the show, with four randomly chosen outputs directly controlling the Synthesis Technology E370 output levels in the Intellijel Amps, while the other four outputs were patched to Let’s Splosh to be spread through the system. Having chaos directly control levels is interesting, because it means you’re hearing chaos and it’s meandering directly, as opposed to indirectly via the modulation of a secondary parameter. When the chaos signals rise, so too does the sound of each oscillator. As the chaos moves through its circuitous oscillations, you can hear its mood. Sometimes bold, other times shy and apt to change its mind, chaos is the highlight of this patch, not part of a side show. I’ve done similar patches before using chaos, most notably Jamuary 2509, but I tend more towards Swell Physics, or some form of LFO over straight chaos for this kind of job. Here, Frisson and its chaos form the basis of everything.
And it’s not just the volume levels that Frisson controlled. The remaining four outputs were patched to Let’s Splosh, a very excellent “put something in, get many things out” kind of module that takes four inputs and has a lovely 16 outputs of completely interrelated control voltage to spread around a patch. Four more-or-less randomly chosen Splosh outputs were patched to the Atomosynth Transmon’s inputs.1 Eight of the 11 outputs from the one and only Triple Sloth were used to modulate the eight CV inputs on Rows C and D of the Transmon to help create a wild mix of chaotically moving control voltage. This rich and complex mix of chaos created all of the tonal movement in this patch, as the oscillators were sent a steady Dmaj7 chord. As voltage increased along the X axis of each wavetable, notes move along a scale, most noticeably in the higher register, where it sounds reminiscent of a classic Gen X toy, the Whirly Tube. I was absolutely infatuated by this chaotically created melody, making sure to treat that one channel different from the rest. I offset the audio in Amps so that it might be audible for a bit longer than the other oscillators. I also made sure that its channel was centered and turned up loudest in the ST Modular Sum Mix & Pan, even if the third channel is still mixed too loud. I wanted it to be a highlight of the patch, with pitch and volume of the melody controlled by Frisson’s lovely chaos. Let’s Splosh didn’t stop at modulating wavetables, however. Two more of its outputs were patched to the two CV inputs on Triple Sloth, creating a CV loop where Splosh modulated Sloth which in turn modulated other Splosh outputs in the Transmon. Chaos acting upon chaos, acting upon chaos. Beautiful.
The audio was patched from the Intellijel Amps to the Addac System Addac814 6×6 Stereo Matrix Mixer via the ST Modular Sum Mix & Pan, before being spread around to various effects. Its primary destination was the Echofix EF-X2 pair for some stereo tape delay treatment. This recording may well be the my most beautiful result from the tape delays to date. Having used offset delay times with varying tape head combinations, a fair amount of feedback, and a smidge of reverb, the sound floats back and forth cloud-like in the stereo field. Once that cloud hit the reverb, it lingers in the best ways possible, with a slight octave up choir to provide for some air.
But the tape delays weren’t the only FX destination for the main audio. As I’ve become prone to do, I wanted something to fill out the frequency range. Most of the audio was in the mid-to-upper ranges, and I’m a sucker for depth. I used Panharmonium with a fairly slow analysis gap, set at an octave down. Two octaves down really sounded great, but, like the last patch, there was too much flutter from very low frequencies. I didn’t want to bother re-patching it through a filter, and I didn’t think to use an EQ in my mixer. I thought about sending the Panharmonium through a delay, but ultimately chose to let it stand on its own (through reverb, of course).
And the effects didn’t stop there either. Another favorite method of mine to thicken sound is to use it with the venerable Pladask Elektrisk Dradd(s). It’s not easy to describe what the Dradd(s) do in Grain Mode. The manual describes it as time stretching. And though it certainly sounds like time stretching, with some sources it sounds like something else too. Almost as if a small string section were playing a tremolo shadow of the input. A wonderful unsteadiness to the notes that follows it around like a little brother whimpering for attention.
With the core of the patch complete, I sought some appropriate ornamentation. This is normally a spot I might use a Multisample piano or high(er) pitched oscillator pings through a LPG, but none of that felt right. It was awkward, often falling too in line with the already existing frequency and timbre range of my chaotic cloud, and just sounded bad. I tried pianos of various types, resonators like Rings, music box samples, and others before deciding to do something I’ve never done before; just cycle through sample folders and see what sounded good in context. I landed on one instrument that sounded promising, but I decided to keep going and come back to it if I couldn’t find anything else. Within a few clicks I landed on a sample folder called “MoogMG1vsAD_SynthFX.” I still have no real idea what these samples are, but when I heard the first careless swirl I immediately associated it with the sound of my Whirly Tube oscillator and knew it was right.
Gate and pitch generation for these swirlies was, just as the main audio, generated via chaotic processes. Four outputs from The Hypster were patched to Numberwang, while two others were patched to the Helvetica Scenario inputs. Numberwang used these chaos signals to create gates, while Helvetica Scenario was used as a sample and hold to get four separate CV outputs to be used for pitch, two of which would be derived from the inputs from The Hypster. Numberwang is a fantastic way of getting off-grid gate generation. It’s a favorite method of mine, depending on the needs of the patch. Four of its outputs were sent to the Disting NT which triggered the quantizer and samples, while two other outputs were used to trigger Helvetica Scenario. Helvetica Scenario is a fun module. It’s a slight twist on a traditional sample and hold module. Rather than using noise from which to sample voltage, it uses a jerk chaos signal running at approximately 300Hz. When hit with a trigger, it will output the voltage of the chaos signal, just as a normal S&H would do with noise. And just as with most S&H modules, one can always use an input, but Helvetica Scenario provides two outputs which act like a S&H. The first, the S&H output will sample the input and send that voltage to its output. The second, the Stepped output, however, will always sample the voltage of the internal chaos circuit so that each will provide two separate stepped outputs with just one trigger, for a total of four stepped voltage outputs. In fact, even if no input is patched, the Helvetica Scenario Stepped and S&H outputs will output voltages from different parts of the signal, so there are always at least two discrete voltages on every trigger. The four outputs here were used as the pitch CV for the swirlies, via the Disting NT’s quantizer, triggered by other gates coming from Numberwang.
The swirlies from the Disting NT were patched to the Venus Instruments Veno-Echo. Cross feedback was set to full, with wide stereo width. There was also a twinge of sample reduction in the feedback path. Two final gates from Numberwang triggered the left and right Reverse, which created a very psychedelic feel to the swirlies as they darted through the clouds of the E370 and its floating repeats, Panharmonium, and the Dradd(s).
I didn’t set out to re-record my latest patch the other day. I was set on using some other sample set in some other way. But there were a few things about my last recording that bothered me a little. I was getting too many pitches that were too high; well outside the zone of what “Low Strings” should be. There were points when way too many colors were being shouted at listeners. The delay was a bit too much. And I wanted to streamline the patch a bit.
I won’t go too in depth on the patch, you can read about the details here, but I did make a few changes that improved the recording substantially….
The most major change I made was to eliminate the Qu-Bit Electronix Nautilus, and use the pair of Echofix EF-X2 tape delays on the string samples. This helped to both fill out the space, while simultaneously cutting away excess in the overall soundstage. Rather than simply repeating notes and phrases, the tape delays lengthened and widened them.
The Panharmonium (introduced at ~2:40) was pitched down an octave, which helped lend some depth. More voices were added, and it was set to analyze a wider spectrum. The Panharmonium, along with the Walrus Audio Slöer (which was also set to pitch an octave down), really added weight to the entire recording. I removed a delay from the Panharmonium’s signal path (previously the tape delays), and allowed it to sing only through the reverb, which was a substantial improvement.
No changes were made to the Dradd(s).
No changes were made to Plaits-does-Robot-Speak except sending it far fewer gates.
As I was un-patching my Fall patch, I got a hankering. I’ve used Multisample Piano in several patches over the last couple of years, but I wanted to make another one with the piano as the focus of the patch, rather than an accompanying ornament. These sorts of patches aren’t terribly hard, but they are fun, and I love relaxing to them as they just play.
My first thought was to get a random distribution of triggers and let it roll. I began by using the same sub-patch that created the Fall emulation; a series of random envelopes cycling within a defined range, with the End Of Cycle trigger striking one of four gate inputs programmed on the Disting NT. That worked okay, but there was something not quite right. I was never able to pin down exactly what that was, but I decided early on to abandon that patch and try a combination of patches that I’ve used before to some really nice effect. Once I decided to switch things up, I knew exactly what I wanted to do.
Let’s Get Fenestrated, by Nonlinearcircuits, is one of Andrew’s newest designs. It’s a triple comparator with the sole job of spitting out gates once the inputs reach certain voltage levels. According to an email exchange I had shortly before its release, Andrew’s idea when designing this module was to create wonky clocks with chaotic sources. When I inquired, I was looking for a couple of tools, some type of comparator being one of them.1 Upon his announcement of its release I had Scopic Modular, the guy I use for all of my NLC builds and all around nice guy, order and build it for me. But despite having had it for a while I hadn’t used it much. In the time between seeking some form of comparator and receiving Fenestrated, I had worked up several patches to get chaotic gates. Numberwang was my primary tool, but also others. But as I started to think about how I would come up with a different clock algorithm for this patch, I immediately thought about using Fenestrated.
The patch started with a chaos signal from The Hypster. I initially went with the U output, because it has the biggest range of the four outputs, but despite modulation happening via patch-programming, the output was just too regular. No matter what I did with the comparator setting on Fenestrated, I got more or less a steady-ish beat. Not on a grid, but just a little too close for the style of gate generation I was going for. Switching to The Hypster’s Y output, and adjusting the window on the first comparator of Fenestrated, fixed that in short order. The new clock output from Fenestrated was patched to Stochaos, which uses chaos (or random, or both) to generate gate patterns. One advantage to using Stochaos is that, unlike Numberwang or using the End Of Cycle outputs on various free running function generators, it generates multiple gates at the same time, meaning I’d have both dyads and chords, along with singularly generated notes, which is not possible using those other methods. Numberwang spits out exactly one gate at a time, and the chances of two random, free running cycles of a function generator finishing at the exact same time is exceedingly low. Having found a good cadence of notes, I moved on to giving them a pitch.
I’m a fan of using a very small number of modules as what I like to call an engine. The thing that makes the patch go. It’s quite often that I’ll use only one or two modules to control an entire patch. Having used The Hypster to control gate generation, I initially decided to use its other outputs as a pitch generator, patching the X, Z, U, and -Y outputs to the Disting NT CV inputs, via the Vostok Instruments Asset so that I might massage the notes for each input into a good range focused on the lower-middle to middle parts of the keyboard. Notes that don’t require one to be a dog to hear, nor ones that often only contribute to a muddy soundstage if used too often, especially in a reverb-rich environment. But I wasn’t completely satisfied with the result, so decided then to use the four CV outputs on Stochaos, which worked wonderfully, even if I can’t explain why it was better.
At first I wasn’t sure how I wanted to ornament the piano, not that a piano and some reverb aren’t enough to be beautiful. I wasn’t set on a sound, so I began to experiment with delays. Normally I would go to the Venus Instruments Veno-Echo, but decided instead to use the Qu-Bit Electronix Nautilus. I wanted intermittent reverse delay, which the Veno-Echo can do, but I wanted to CV control the reverse parameter, and not simply gate it on and off. Although I don’t always appreciate prescriptive controls, if those controls are lightly modulated the result need not feel prescripted. With most delays, reverse delay is reverse delay. It’s on or off. But due to it having up to eight delay lines, the Nautilus takes a different approach. Rather than an on of off dichotomy, it prescriptively assigns reverse repeats as you turn the knob. At full counter clockwise there are no reverse repeats. But as you turn the knob clockwise, you get reverse repeats in patterns. From the manual:
I set the knob at just above full CCW. I wanted reverse repeats, but I didn’t want them to overwhelm regular repeats. Using an attenuated version of one of the Triple Sloths outputs (a medium length cycle) I lightly modulated the reverse knob, which ended in a wonderful mix of mostly forward repeats, augmented by the always beautiful zips of reverse delay. But it wasn’t quite enough. I wanted to make it a bit dusty, so chose to put a very light amount of sample reduction as the Chroma.2 This matched perfectly with the slow clock speed I had running on my reverb, the Walrus Audio Slöer. I next decided on how long of a delay I wanted, and ultimately went with a fairly long delay time, and used an internal cross-feedback pattern for the repeats.
Wanting to fill in some of the space, I decided to go with a combination of Panharmonium and the Dradd(s). I initially had an idea that I would pitch the accompaniment in opposite directions, Panharmonium down an octave and the Dradd(s) up an octave, but that created all kinds of sonic havoc, especially with the already pitched up reverb. It just was too much going on in too many frequency ranges to be coherent. One issue with this patch is that it’s a bit difficult to pick out the Panharmonium. It’s pitched downwards an octave to give the piece some depth, but it seems to get lost a bit. It’s noticeable when Panharmonium is not present, especially as I added some saturation via the Echofix EF-X2 pair towards the end, but it’s hard to pick out as a separate voice in this recording. I’m not sure whether that’s good or bad, though I tend towards wanting every voice to stand on its own. I’m not exactly sure why this voice is so buried in the mix, and I’m not sure if it’s a bad thing in the end, but it is a little frustrating.
The Dradd(s), however, came out exactly like I’d hoped. They were set to Grain Mode, and time stretched at a slow crawl, one channel in reverse, the other forward. I love granular synthesis. The textures it can create are wonderful, and this patch is no exception. Each piano note, and its successive repeats from the Nautilus, stretched to the furthest extremes, filled out space in a particularly interesting way that I found compelling; the Piano notes seemingly stuttered as they were dragged out as long as the Dradd(s) could manage. Not only did the Dradd(s) serve to fill in space, but they added a wonderful lo-fi texture to otherwise smooth piano notes. Beautiful.
One thing I’ve long wanted to experiment with is using multiple reverbs. Not simply stacking reverbs or using two (or more) in parallel, but by trying to use them as instruments unto themselves. I’m not exactly sure when I first heard this technique, though it was surely in the context of ambient guitar, but it wasn’t until I heard Music Major by A Last Picture From Voyager that I saw its full potential. I recently made a recording during which I featured the freeze effect from the Dreadbox Darkness, and it was great, even if it all started with an accident. I was mesmerized by the beautiful reverb tail hanging as if it were a mist. But despite initially patching in the Darkness, I was simply unable to find the same kind of magic present in that first recording. While trying to fiddle around with Darkness, I discovered that, with shifting soundscapes, timing is everything. Hitting the freeze switch a smidge too early or too late and the capture isn’t what one hoped it might be. Whether too soft or too loud, slightly dissonant or too plain, hitting freeze at just the right moment proved to be more difficult than I originally imagined. So I decided to try a new reverb that I got around the start of the year but hadn’t yet used, the Old Blood Noise Endeavors Dark Star Stereo, to see if I might be able to get better results.
Buying the Dark Star Stereo was a long time coming. OBNE has been making highly compelling effects pedals for a long time. Alpha Haunt, a flexible, nasty fuzz,, was my first foray with them. And even if I sold that pedal for something much more basic, I knew it sounded awesome and that I was totally into the OBNE ethos. Dweller (Dweller!) was my next OBNE purchase, and that thing is ace. A delay circuit inside of a phaser circuit that sounds both unique and beautiful. Next was the Rêver and its sibling, Minim, which are both absolutely brilliant reverse delay/reverb. But as I grew, and especially with modular, I was pretty adamant that my reverbs all be stereo, and despite having wanted to use OBNE reverbs for their unique tones, none of them were stereo. A little while back they released the Dark Light (now discontinued), which is a “stereo” mashup of the Light and Dark Star pedals. But I always felt the implementation was odd, and some sounds were disjointed. It was seemingly more a dual mono reverb than a stereo one, and it just didn’t sound right so much of the time. So I waited. Then a few months backs, OBNE finally released a true stereo reverb, this time a fully featured version of the Dark Star, their most popular reverb pedal (and my favorite of those I’ve heard), and I jumped on one almost immediately. When I bought it I knew I didn’t have room in my pedal rack. But after selling my Oto trio and getting the proper cables to patch it into my synth, it quickly made its way to the synth FX rack, even if I all but ignored it during Jamuary when I didn’t touch it once.
The Dark Star Stereo is a lo-fi reverb, complete with pitch shifting (up or down), filtering, saturation, and sample reduction, along with mix, volume, and stereo spread. It’s designed primarily for soundscape and pad generation, but works great on any source. The default sound without any pitch shifting, filtering, sample deduction or overdrive is soft and gentle. But once you begin to shape the sound it begins to texturize in haunting ways. A bit of crunch to add some dustiness here, some high pass filtering there, and you have a beautiful ambient reverb that can last for days. In this patch I used a smidge of sample reduction and high pass filtering, along with pitch shifting up an octave. Compared to other implementations, the pitch shifting feature is…different. Rather than a cheesy sheen or beautiful choir-like effect, Dark Star Stereo produces more of a granular sounding pitch shift that can be a bit jagged sounding (in good ways), though I do wish that one could control the amount of pitch shifting in the output so that I can more easily get less of it. In this patch the Dark Star Stereo is introduced briefly at about 3:25, a second time around 4:35, then I used it very subtly as a parallel reverb from about 5:18 through the end. The result here was “okay.” It wasn’t exactly what I’d hoped for, but it was a good first foray into using reverbs in this manner., and a step in the right direction for future exploration.
The end-of-chain reverb in this patch is the ever-beautiful Walrus Audio Slöer, with a smidge of its choir-like pitch shifting that is exceptionally beautiful. The Slöer has been my go-to reverb since receiving it, and I simply can’t envision not having one.
I also inquired about a gate combiner, to which he responded that would be a good idea, and wrote back a couple of days later with the design for Gator. ↩︎
Chroma is an effect that’s applied to the delay feedback path. Other effects are a LPF, HPF, saturation, wavefolding, and heavy distortion. ↩︎
During one Jamuary patch, I had the pleasure of using the Alexandernaut Fugue Machine Midi sequencer extraordinaire. I enjoyed it so much that I sought a MIDI > CV converter so that I could bring that particular brand of magic into my synth. Sequencing is easily the most challenging part of eurorack for me. I’m quickly learning that, at least in the immediate term, “battleship” sequencers and me don’t work well together. The options are oftentimes overwhelming and programming them can be a constant exercise in frustration. When you’re trying to play a polyphonic patch, these frustrations compound as the patch gets more and more complex. Of the large sequencers I’ve used René v2 is easily my favorite. I find it to be the most intuitive sequencer I’ve used. The sequencer in the Doboz T12 is also easy to catch on, and the Verbos Voltage Multistage is ultra-simple. But I’ve done nothing but get my teeth kicked in by some of my larger sequencers. Frap Tools USTA, Oxi One, and 4ms Catalyst Sequencer in particular. Perhaps it’s the lack of effort with learning them, or that I simply quit on them too quickly, but nothing kills a moment like manual digging in the midst of a patch. Fugue Machine, even if it’s walled in its own very small box, is but one of many tools that make sequencing much less of a chore, and can help spark the creative drive to explore more advanced sequencing. Fortunately, there are good ways of leveraging MIDI tools in Eurorack.
I searched for a couple of weeks for my ideal MIDI > CV converter. My main consideration was for sequencing polyphonic patches, so it needed to have at least four channels of pitch CV, gates, and velocity. There are several options. One of the more compelling options is the Der Mann Mitt Der Maschine DROID. It’s a CV generating and processing powerhouse that can do almost anything that can be done with CV, including MIDI > CV conversion. I even have a DROID, and it has a killer feature set. If you can program it. It turns out that I can program DROID. It’s not terribly hard, even if I still do it by hand rather than using the GUI tool to create patches. But DROID would take more space, and would only be useful in this capacity, needing all eight CV outputs for pitch and velocity CV. So I kept searching, and finally settled on the relatively new Befaco MIDI Thing V2. I already have and use the Befaco CV Thing CV > MIDI converter and find it good at its job, even if the screen is not fit for middle-aged eyes. It’s only 6hp, and can sit right next to the CV Thing.
One of the MIDI Thing’s features is that it has 12 outputs. Exactly enough for four voices worth of outputs, and what’s more is that the exact configuration for my initial intentions with MIDI > CV conversion is already saved as a preset, or Pre-Def in Befaco-speak, for quick and easy input and output configuration. I simply set the MIDI Thing to “Predef 2: Multi Timbric” in the Global Menu and it automatically set the incoming MIDI channels to 1-4 and preconfigured the outputs. Pretty slick. Since I was already in for a lot of patching, I opted to forego using the velocity outputs. That wasn’t a step I was terribly interested in today. I wanted pitch CV and gates to trigger envelopes, and by golly that’s what I got after spending less than one minute in the MIDI Thing configuration screen.1
Once I had my MIDI routed in the AUM MIDI Matrix, and properly set MIDI ”Predef-ed” in the MIDI Thing, I fired up Fugue Machine. Since I was testing the functionality of the MIDI Thing and how that would work with a modular system, I wasn’t overly worried with an elaborate, or even original, sequence, and just used one of the included presets. Although I had played with the sequence length and transposition while running through the patch before recording it (which was all supremely cool), I simply forgot when I improvised the recording. I was more preoccupied with timing each channel, the levels of each oscillator, and crossfading the ending. As a result, this recording is a repetitive sequence. It doesn’t repeat exactly because of the modulation, but there’s no variation in anything other than oscillator timbre.
For oscillators I chose the always excellent Synthesis Technology E370, with a User-Loaded Wavetable titled NOV that was left from a previous owner. Thanks, dude. It’s pretty outstanding. Tuning each oscillator to unison (in Morph X/Y mode), I ran each of the pitch outputs from the MIDI Thing to the v/oct inputs. I followed that up by using the eight outputs of the Nonlinearcircuits Frisson to modulate both the X and Y parameters of each wavetable for all four oscillators. This constant timbre changing caused by the modulation also causes dramatic volume changes as waves morph in and out of more and less prominent waveforms in the table. I initially wanted something glitchy, and turned Glitch on HIGH with Interpolation Off for each of the four channels, and while it was cool, it didn’t fit at all in with the overall tenor of the sequence itself. The tonality is too “positive”, being in the key of A Lydian, and the sequence too upbeat. I suspect it would work fantastically on slower, more drone-ish material.
After I routed the pitch CV and modulation, I ran the gates to two Frap Tools Falistris for some enveloping. In addition to being enveloped at the Control inputs, three of the four gate outputs were also multed to the Hit input on one of two Rabid Elephant Natural Gates to provide some beautiful pinging of these ever-changing tones coming from the E370. All four channels were processed through Natural Gate, but only three were pinged. The bass note was only enveloped. In this process I made a grievous oversight. While Falistri is a perfectly good tool for this job, particularly the pluckier notes, more defined shaping with a ADSR would have really served the slower voices well. It so happens that I have perhaps the most advanced ADSR generator in Eurorack, but I didn’t even think to use it, and when I did, I was way too deep in the patch to re-patch and reconfigure the envelopes, so I let it go.
To be honest, I was expecting hurdles to cross, but I was surprised when it all just worked. CV did what it’s supposed to do. Gates did what they were supposed to do. Everything was perfectly in tune and on time.
Once the notes were created in their respective Natural Gate, all four outputs went to the ST Modular Sum Mix & Pan. While three of the four channels were panned to mono, the fastest moving and highest pitched voice was being slowly panned in the stereo field. The stereo output was then routed to the Addac814 6×6 Stereo Matrix Mixer, and sent to the Venus Instruments Veno-Echo. To ensure a solid clock for the delay, I used the now-defunct (or at least unavailable in the United States according to the App Store – which would seem weird) CoVariant Clock AUv3 plugin, which converted the MIDI clock in AUM to CV and sent it out an ES-9 output as an analog clock. I’ve never really sought to use a MIDI clock as the master clock outside of the iPad. I’ve certainly never used it as the master clock in a Eurorack patch. But this clock was flawless, likely to due CV being generated directly at the source, minimizing switches and pass-thru cabling or USB MIDI jitter. Hopefully CoVariant remains a working plugin in iOS for a while to come as there are currently no other direct MIDI > CV clock converters on the iPad. Veno-Echo was set at x2 on both sides with similar feedback just shy of noon. I also added a smidge of drive in order to enhance the sample reduction I put in the feedback loop. Veno-Echo, with its cross-feedback and width parameter, really can create an enormous stereo field
And so can the Dradd(s). It’s no secret I’m absolutely smitten by dual Dradd(s). Despite this infatuation, my first instinct was to patch in Beads, but Beads just didn’t really have what I was looking for today. At least I couldn’t find it. But the Dradd(s) did. In fact, I had to decide between two modes which both had something very cool to offer. I ultimately chose the Tape mode because the octave up was too much to resist. I slowly started to fade out the oscillators once the Dradd(s) were at full volume, and allowed its magic to guide the rest of the recording, fading out in a glorious wash of the Rain algorithm on the Walrus Audio Slöer.
When I turned on my Make Noise synth tonight, I had anticipated some more experimentation with filter wobble. I had both QMMG and QPAS right in front of me, and so far in my brief experimentation, these two filters had been the best at it. And I did do some of that. It was the first thing I did for about 30 minutes. But, as it so often does, the patch sent me in a different direction. It’s still a delicate patch, but not in that kind of way.
This patch won’t get the full patch breakdown, but I’ll lay out the basic framework.
René X Channel > Spectraphon B (stereo outputs) > QPAS (Smile Pass ) > X-Pan Spectraphon B (Sub) > QMMG Ch 2 (LPG) > QMMG Ch 1 (VCA) > X-Pan The recording starts out with only the QPAS outputs, before bringing in the LPD’d version. Both are crossfaded once the LPG’d version is brought in. The resonance, particularly on QPAS, got a smidge out of hand, but nothing ear screaming or offensive.
René Y channel > Spectraphon A (stereo outputs) > QMMG Ch 3 & 4 (LPF) > X-Pan (Aux) This is the slower, lower voice that was brought in last. Spectraphon’s A side Focus and Slide were modulated by Wogglebug. Once bright in, this voice was only level controlled by the cutoff of the filter in QMMG. I slowly brought up the envelope amount in Maths to open it further and further.
X-Pan (stereo outputs) > Mimeophon > Output
Maths is doing a lot of work, modulating the filter cutoff of both Both QPAS and QMMG, Radiate on QPAS, controlling the envelope level to the QMMG in LPG mode, as well as the crossfading of the continuous playing sequence and the pinged one. I need to find a better way to activate the crossfader. Since I was using a copy of a Maths Unity output in both of X-Pan’s Crossfade CV inputs, I couldn’t just attenuate it to 0v then introduce the crossfading by turning a knob. So I inserted the cables when I was ready to introduce the voice. You can hear that little fumble as that voice is brought in.
I used a reverb send from my mixer to the Maneco Labs Otterley Reverb for some reverb (duh) as well as a touch of granular treatment.
One of the beautiful things about eurorack is the many happy accidents that we all run into on occasion. Those times when some combination of conditions present at just the right moment seems to produce something magical. You don’t necessarily know what got you there, but nonetheless, here it is and it’s glorious. Though we may not always know exactly what leads to these enigmatic moments of splendor, there are things we can consider when seeking to be able to use those sounds as part of your artistic arsenal. It’s one thing to hap into something beautiful, however you might describe that term, but it’s another thing altogether to reproduce whatever it is you heard to make that magic an intentional part of your sound. To play it, rather than have it fall in your lap.
A couple of days after Jamuary concluded I made a patch on the Make Noise synth that made me stand up and stare. There was a whisper. An oscillator speaking softly into a filter’s ear, quivering as it tried to muster enough courage to get sound out. It wasn’t unlike bowing a string as lightly as possible, or trying to play a wind instrument as quietly as one can. There was a vulnerability in the voice, seemingly lacking the confidence to speak, or like trying to speak when you’re crying and your lips quiver. There was a wobble that was absolutely intoxicating, and I was set on trying to reproduce that wobble.
When I first set out to try and recreate this sound, I first isolated the conditions of the patch I wanted to emulate. Of course oscillators can’t speak softly. They only know one output level, generally speaking. I documented every patch connection and knob setting from this sub-patch. I verified modulation sources and any peculiarities. I thought about this patch a lot, writing extensively in my Notability patch book, and narrowed it down to three factors. At least theoretically.
As low a level going into the filter as possible. On my original patch, I used QPAS as my first filter, and controlled levels with the input VCA knob. I initially did this out of necessity because the other voice in the patch was very quiet by its nature, and when any real level was given to the oscillator going through QPAS it was too loud. I discovered later that night that the lower the level, the better the conditions for interesting wobbles. If your filter does not have input level control, you can use an attenuator or VCA before going to the filter input.
A filter with some fairly aggressive resonance. It need not scream like a Polivoks, but the resonance needs to be pronounced before it goes into self oscillation. If the resonance is non-linear, it’s even better. I’ve also surmised, perhaps errantly, that a vactrol-based filter would be better suited to this job because of the inherent drag and voltage drift of vactrols. The filter creating pronounced wobble in my Make Noise patch was QMMG, a vactrol-based filter, processing a signal that had already gone through QPAS. I could be wrong, but my experiments trying to reproduce the wobble seem to bear out this conclusion. I don’t have a vactrol-based filter in my main synth, but none of the filters I used in my experiments had the same sort of wobble as that produced by the QMMG.
A slow moving modulation signal that moves the cutoff frequency through the fundamental frequency of the note. I’ve found the slower the better, but there are diminishing returns to that proposition. When you add resonance to a filter, you’re creating a small hump in the EQ curve at the cutoff frequency by feeding it back into the filter’s input. When that cutoff frequency intersects and passes through the fundamental frequency of whatever signal you’re passing through it, you get a small wobble. The resonance itself and the modulator’s frequency and shape can alter that wobble some, and can change its character, as do any curves you might put on your modulating signal.
Of course all of this was theoretical, and much of it still is, even if I’ve received some form of verification via Google AI, and tangible signs that I’m on the right track through my subsequent experimentation.1
When I set out to make a patch yesterday, my goal was to first experiment with recreating filter wobble through my main synth where I have a plethora of filters of all sorts. My first thought was to experiment wholly within the Frap Tools Cunsa. I can create sine waves with the first filter and still have three filters with which to experiment, all with normalized patching to make things simple. I was pretty quickly able to create some wobble using my three guideposts listed above, but it was very consistent, and exciting as it was to know I was on the right path, I felt that perhaps the Cunsa was simply too polite a filter to get the best results. Abandoning Cunsa, I next went to the Joranalogue Generate 3 feeding Filter 8, but I never felt like I could get anything close to what I wanted. The cutoff was always too high, and I couldn’t tame the harmonics in a way I wanted. So I switched to a single sine wave from Filter 8 feeding the Bizarre Jezabel Seju Stereo, which was okay, but not special, so I went to the Pkhia, which didn’t work very well. I moved on to the Pkhi Mk3, and had a promising start, but it didn’t progress much. Finally I went to the Blossom, a multi-output filter inspired by the legendary Mannequins Three Sisters, and I heard…something interesting. The wobble was there, and had a bit more character than the simple hump like the rest of the filters. I had found the subject for the rest of the day’s experiments. I spent well over two hours exploring different filters, and of those I tried, a simple sine wave into Blossom was definitely the most compelling. I have other filters that I think are good candidates, namely the Verbos Amp & Tone and Instruo I-ō47, but neither of those cases were in the synth when I turned it on. I’m definitely interested in trying those filters, as both have just the right kind of resonance, I think, to be compelling options.
After I’d finalized a base sound I wanted to use for the rest of the patch, a single sine wave into a resonant low pass filter, I worked up a sequence in C Lydian on the very excellent Doboz T12, and went to work. Like the voice used in my Make Noise patch, this voice would also be completely un-gated, sauntering along, only being level modulated in the filter by the slowly moving function of a cycling Contour 1. The cutoff point is set lower than the lowest fundamental frequency so that there would be times when no notes of the sequence come through. Because Blossom doesn’t have level input control, I ran the output of Filter 8 through an attenuator to initially make the sound as quiet as possible while still being (mostly) audible.
I decided to use a staggered clock. One that is gated by a clock divider, so as to never have continuous repetition. I multed a single x1 clock output from the Sitka Gravity to the Nonlinearcircuits Divide & Conquer in order to create my gate. Because the Gravity is in its infancy, there are several basic things it can’t do. As of now, Gravity’s clock (and sequencer) only outputs triggers, and not gates, so I couldn’t use the duty cycle of a gate output (like those on Pamela’s Pro (and New, and OG) Workout) to gate the x1 trigger that would ultimately go to the clock input on the sequencer. I wanted the clock to start and stop every five beats, and Divide & Conquer was able to provide a gate that enabled that staggered clock for my sequence to follow. The sequence itself is simple. It’s a couple of scale lines going up, with a very low probability (11%) of getting a quantized random pitch within seven semitones (a fifth) of any given step of the sequence. But because the cutoff frequency of the filter goes below the lowest fundamental pitch, the sequence flows in and out and isn’t steady. Notes hold in beautiful ways, and the sequence doesn’t repeat despite being only 16 steps long.
Once through the now occasionally wobbling filter, the audio went straight to the Bizarre Jezabel Mimosa. Mimosa is what I consider to be the most beautiful distortion I’ve heard in any format, short of very high dollar guitar amps. Of course the word beautiful is doing a lot of heavy lifting here, but what I mean is that it can heavily distort something, while still allowing the source to shine. It adds life, even when the dials are pinned. No matter what, you can always let some of the original dry signal through which helps keep shape in the audio regardless of the amount of distortion is applied. From gentle piano notes and sine waves (such as those in today’s patch) to ripping saw clouds Mimosa just does the right things whether using it for some gentle saturation or full on sonic destruction.
In this patch Mimosa started gently, with both the output volume and distortion amount both turned low. As the piece progressed, gain was adjusted upwards at multiple points. The first place was the original audio signal on the way into the Blossom. This allowed its resonance to growl a bit more rather than wobble. Higher input levels into the filter also mean higher output levels from the filter, and Mimosa is very sensitive to input level. Even at the same knob settings, input level is a crucial determinant of the final sound. Lower levels at the input might just have a bit of coloration or slight crunch, whereas loud sounds will rip or soar. It’s part of Mimosa’s magic. After I adjusted the initial input as loud as I dared, I started to slowly raise the output volume and distortion amount on Mimosa, as well as the amount of wet signal. From gently whispering and quivering to finally finding one’s voice to sing, all from nothing but subtle gain changes along the way. From Mimosa, the audio went to a new addition in the synth; the Addac Systems Addac814 6×6 Stereo Matrix Mixer to be distrusted to several effects.
It should be reiterated here that every sound is this patch arises from one single sine wave fed by one simple sequence, with but a single parameter being modulated by a lone triangle function (the filter cutoff). Of course that isn’t the only sound in total. That lone sine wave is repeated all over the place with overlapping delays, looped with four simultaneous digital tape heads and a delay of its own, and reverberated. The first delay, a Bizarre Jezabel Quarté Mk2, mostly added some lovely texture. A bit of a wash of decays in the wake of the melody, its gritty tail disintegrating into nothingness, which added depth and color. Repeats were set to moderately long, with a slow(er) delay time. With the PT2399 delay chips, the longer the delay time, the noisier it will be. The second delay was an Olivia Artz Modular Time Machine, with 4 active taps. It’s clear digital voice echoing the distorted sines near perfectly. Both delays are set to different times which really served to fill out space and maximize this one simple voice with the most basic of sound waves.
As beautiful as this very simple sequence was, I wanted to see if I couldn’t perform some complimentary embellishments, and decided to once again delve into the Cutlasses Instruments Gloop. I’ve only used Gloop a couple of times, but it’s already captured my attention. Some modules take some time to gel with. Despite some sloppy transitioning in my first couple of uses, I immediately took to Gloop. Its interface is (mostly) intuitive, and it’s a capable looper with some very cool tricks. It’s pretty easy to create compelling loops with Gloop. That said, it does have some drawbacks, at least in its current iteration. Though it’s packed with some clever effects that can be eminently useful with a looper, delay, reverb, and a host of tape-related effects like tape degradation, wobble, noise, and saturation, these effects can only be used on one channel or the other, and not both. Though Gloop has two outputs, it’s not really stereo, but dual mono. Each of the four heads can be panned in a stereo fashion and be used in one or both outputs as if it were a stereo signal, but for reasons I don’t understand the effects can only be used in one output at a time. This imbalance can definitely be a problem when trying to create a consistent stereo field. I was hoping to use the degradation effect, wherein the audio degrades as it would on a tape machine with each successive loop, fading out to nothing after a time. In loopers this is generally simulated by constantly low passing the signal at progressively lower cutoff frequencies in order to gradually roll off the highs. It’s a crucial component of Frippertronics, for instance. Allowing a loop to fade to nothing is also a beautiful way to end a track, and unfortunately I can’t do that with Gloop while using both output channels. In lieu of using Gloop to add tape hiss, I was able to add noise to both channels in the mixer via the very excellent DAW Cassette by Klevgrand, but that was an improvised half-measure. I think I can patch a workaround, but it definitely won’t function in quite the same way. A slow moving negative function into a wide open filter cutoff should get me at least part of the way there. Timing would be an issue. How long should this envelope be? What happens if I get to the end of the function, and I haven’t pressed stop on the recorder? Will the cutoff reset to fully open? That would be bad. But those are problems for another day.
I recorded a length of the sequence to Gloop, then while the sequence continued to play configured the four play heads and slowly started to raise the level on the looper, while lowering the level of the continuously sauntering sequence. Though this transition isn’t perfect, it’s much smoother than in tries past. I would use a crossfader like the WMD AXYS to more smoothly move between the two parts, but because the individual voices were being multitracked separately, I crossfaded in the mixer by hand using the Michigan Synth Works XVI Faderbank CV and Midi controller. The first and fourth heads were hard panned left and right at 2x forward and 4x in reverse respectively, while heads two and three were panned in the middle at 1x forward and .5x forward. I manually played the loop size and location within the loop of all four heads until it I manually faded out the hard panned parts before fading out the base melody and its half speed sibling. But not even Gloop was without its own dedicated delay, the ever-excellent Venus Instruments Veno-Echo. I used a x4 output from Gravity, with a /3 clock division set in Veno-Echo, which gave me a dotted eighth note delay, an always interesting pattern.
Both voices were mixed together in AUM and sent to the Walrus Audio Slöer using the Rain algorithm with almost no diffusion, and the clock speed at its slowest, adding to an already textured outcome. A medium long decay and high modulation finish off the track.
I put very little stock in the accuracy of AI at this stage in its development. However, it stated the same three conditions I had independently surmised, and so choose to engage in a bit of sweet, sweet confirmation bias. ↩︎
I had to work long hours today, and my back hurts bad, but I still wanted to put something together to keep Jamuary plugging along. Normally on days like this I would have done a quick patch on the iPad, but today I decided on a reasonably simple Make Noise feedback patch, using a very similar patch to my first feedback exploration. I need work on my feedback patching, but there are definitely many nice parts.
The quick and dirty notes:
QPAS L LP output > Mimeophon L Input Mimeophon L Output > Output mixer AND QPAS L Input Mimeophon R Output > Output mixer
With this configuration you’re monitoring from the Left and Right Mimeophon outputs. I also added a dark and dirty reverb, the Maneco Labs Otterley, before going to the output for a little extra murkiness.

As a result of acquiring both the Synthesis Technology E370 and the Flame Instruments 4VOX, after also getting the Humble Audio Quad Operator and RYK Modular Algo earlier in the year, I’ve been stringing together a series of chord-based polyphonic patches using various forms of slow modulation to control the volume of each chord tone. From standard LFOs to chaos, and stochastic functions to ocean wave simulations, I’ve tried at least a dozen of this style of patching over the last several months. Some of these have used static chords that don’t really move anywhere. Different notes of a chord come in and out chaotically (in most cases), but the chord itself doesn’t change. Others are based on the harmonic series, where only one pitch change of the master oscillator affects all of the individual harmonics resulting in chord changes. All of those were composed using chaos or random as a pitch source. But, with one exception, it wasn’t until this patch that I used the NOH-Modular Pianist with real intent and composed a chord progression to move the piece along. To set a mood and provide some tension and relief with harmonic motion in addition to volume and timbre changes. And this time I went big with using all eight CV outputs, rather than just four.
The NOH-Modular Pianist is an interesting module. It promises a world of harmonic movement in an environment where using chords isn’t a simple proposition. Polyphony in Eurorack is equipment and labor intensive. Each separate note of a chord requires its own separate oscillator, function generator, and VCA, at minimum. and requires its own discrete signal path. That’s a lot of patching for what is an easy task in a DAW or by using keyboard-based synths. It’s a lot of tuning (and re-tuning); lots of signals to tweak, and lots of modulation to account for. Before the Pianist, ways to get this sort of advanced polyphony was hard to come by. You could use a MIDI > CV converter, which has its own challenges, or else by painstakingly programming a pitch sequencer note by note, which requires a level of music theory knowledge that most don’t possess.1 MIDI > CV converters require careful calibration, and there are few sequencers with more than just four channels. But the Pianist is different.
Rather than programming chords note by note, Pianist uses standard western music shorthand for identifying chords, and the module does the rest. When you program it to play a CM7 chord, for instance, it knows to send out pitch data for C E G and Bb. It’ll even repeat chord notes in a different octave if no color tones are used. You can add two chord extensions beyond the 7th, called Colours in the Pianist, or use chord inversions to designate the third or fifth as the bass note in the chord. If a up to six note chord can be played on a piano, it can be played by the Pianist.
Users can freely enter chords from scratch in Free mode, or, to make the job even easier, set it to Scale mode and choose only from chords within your chosen key. The scale can be set to Major, Minor, or any of the modes2 and Pianist does the rest. So, for example, if a user in Scale mode were choose A Major as the scale, Pianist would present you with only AMaj, Bmin, C#min, DMaj, EMaj, F#min, G#dim, the diatonic chords in A Major, in order to facilitate easier chord progressions for theory novices. As long as your oscillators are tuned, your chords will be in key. Nifty. For those who want to use chords outside of a key, or if your composition isn’t really in a specific key, Free mode allows for creating chords from scratch. Virtually any chord is possible (up to six notes). In both modes, harmonic complexity is simple, with up to two color tones available, and made even simpler in Random Gate mode where each gate received will add random colors automatically, and choose colors that make harmonic sense within that chord. The workflow in creating chord progressions is intuitive. I was quickly making fairly complex progressions with repeats and skipped chords with ease.
Though Pianist is a boon to those of us seeking access to polyphonic 12TET harmonic movement in our Eurorack patches, it does have its weaknesses. Though you can move notes up and down in octaves to create chord depth, it’s done in a haphazard way. Rather than setting each note for the exact voicing you’re looking for, you have to rely on functions Pianist calls Shift and Spread in order to get full, rich chords that don’t clutter a particular part of the audio spectrum, but it’s not exactly clear how that affects the chord as a whole. I can hear changes, but can’t always identify them. Easy variety, however, can be achieved when the Gate mode is set to Spread. No chord will be voiced exactly the same which creates intrigue.
The calibration for the module, at least in Version 1.0, is straight funky. This patch uses eight discrete oscillators. While tuning I sent a C from Pianist to set a baseline. But in order for the oscillators to play the C being sent, they each had to be tuned to G, which I found odd. The newest firmware, 1.2, addresses tuning and scales in a way that version 1.0 does not, which is a great improvement by all accounts, even if I haven’t used it yet to note any changes. Since I’m using Pianist in Free mode in this patch, however, there wasn’t a compelling reason for me to upgrade, though I certainly will now that I’ve finished recording it, even if I have an aversion to the upgrade processes of most digital modules.
The screen has a lot of information, and not a lot of room. However, navigation is still reasonably simple and the information on the screen laid out such that it’s not hard to read. It’s easier to read and use than many far more established modules like the Disting Ex, Kermit Mk3, or uO_C, even if there isn’t a lot of screen real estate. The interface is super easy to navigate using the mini joystick/push button. Version 1.2 is reported to have an even more streamlined navigation and menu system. Though altering global settings like the Scale, Gate or Spread behavior requires some menu diving which is never fun, programming chords decidedly does not. It’s a point and click operation made easy with the joystick, all done on one level. Move the cursor to what you want to change, click, move the joystick to the desired value, and click. Done.
A major issue with version 1.0, which may have been changed, is that it always boots up with the first saved sequence. Unless you save your progression to one of the user slots, you will lose your work if the module power cycles. If you don’t have much in your progression, or it’s a super simple that’s no problem. But if it’s long or has a lot of direction you might be losing a lot. Ask me how I know.
Pianist has its own clock that will change on each beat, along with a clock output to trigger envelopes or some other event as chords change. But it also has a clock input, which will move along the chord sequence with every rising edge like any standard step sequencer. Being that I rarely use a steady clock, I haven’t tried the internal clock, and have instead used clocks created by chaos or some other irregular source. This patch used a fairly complicated sub-patch in order to derive the chord changes. I didn’t want haphazard pitch changes in the midst of notes actively being played, but only when nothing was being heard. Finding an approach for this was time consuming, and although there are probably (certainly?) other methods that would work as well, I settled upon an approach using two comparators, one analog and one digital.
The four waves from Swell Physics first went to the Xaoc Devices Samara II. Samara compares all four inputs, and outputs the Maximum signal (AKA Analog OR). Being that these four waves were controlling the volume of the individual chord tones, it occurred to me that once the Maximum signal went below 0v meant that all four parent signals were below 0v, which meant no volume at all from the chord voice. This is exactly when I want to trigger the next chord in the sequence. I then sent that Maximum signal from Samara II to a digital comparator, the Joranalogue Compare 2, with its compare window set to anything below 0v. So once that Maximum signal went below 0v, it would spit out a gate that would trigger a chord change in Pianist.
The eight chord tones created by the Pianist went to eight different oscillators. The root, third, fifth, and seventh (or fifth if there is no seventh) form the base of the chord and all go to one of the four Flame Instruments 4VOX oscillators, while the color notes and two additional root notes, one that follows chord inversions and one that does not, all go to a self-frequency modulated Frap Tools CUNSA, where each filter is set to self oscillate, and pinged in a Natural Gate.
The Flame 4VOX has been around a long time. My brother, a house sound engineer, producer, and DJ who’s been into Eurorack a long time, lusted for one long before I even knew what Eurorack was. It’s a fully polyphonic, wavetable oscillator beast, split into four sections of up to four oscillators each. Each oscillator can create detuned swarms, chords, or be unison. Each oscillator can be controlled by v/oct CV or midi, and is fully polyphonic with its own output. It really was a very advanced piece of gear for its time. It still is, even if it hasn’t been updated in several years and is showing its age. There are two pots and two CV inputs per oscillator that can control several parameters including scanning the wavetable, detuning, amplification, and more. It has internal VCAs to control volume, but I did not like how they functioned at all, and opted to use external VCAs, which worked to my benefit allowing me to modulate two wavetable parameters rather than the volume and only one parameter. There are also separate FM and reset/sync inputs per oscillator, along with its individual output. Even if CV-able options seem to be limited, virtually every facet of the 4VOX can be addressed via midi, although I haven’t used it with midi at all. It’s a very powerful oscillator bank that can cover lots of ground.
Although I wouldn’t say programming the 4VOX is difficult, it’s not as easy as most more modern interfaces. The screen is bare bones with low resolution and a slim viewing radius. The encoder is a little weird. You have to push it down and turn CCW to move downward in menus, while you simply turn it CW to change parameter values inside the menu. As a unit, it’s impressive. There are lots of options, plenty of stock wavetables to choose from, and it sounds good, but it shows its age. Upgrading firmware is a laborious process with modern computers. Although you can install your own wavetables, the processes to convert them to the right format and get them loaded can be a nightmare, particularly if you’re a Mac user. All of the computer-side software is a decade or more old, and workarounds are sometimes needed. I’m not a “I need to load my own wavetables” kind of guy, and my unit came to me with the latest update, but if I were that guy or my unit hadn’t already had the latest firmware, it would not be an easy task. I’ve had similar problems with older gear before3, and they’re no fun.
The 4VOX forms the base of the chords, brought in and out by the four waves from the Addac508 Swell Physics. The sound is both powerful and delicate, with each quadrant set to four slightly detuned, unison oscillators, each one being slightly modulated by the Nonlinearcircuits Frisson. Although I was pleased with the 4VOX’s performance, the Synthesis Technology E370 is a better overall option. Although the E370 is also based on nearly decade-old technology, it’s still a better user experience. The screen is in color, fully customizable, bigger, and gives more information. The stock wavetables are a gold standard. The software UI is easier to navigate using a more standard encoder. The physical UI is also far better arranged. With the 4VOX, the screen is in the middle of the module, knob locations are not symmetrical, and are more difficult to wiggle once everything is patched up. The E370 has everything laid out very neatly. The screen is on the far left, I/O on the far right, with knobs in the middle, leaving more than enough room to wiggle. It’s really a premium user experience. The only advantages the 4VOX has are its price, size, and complete polyphonic midi capabilities. The 4VOX has always been less expensive than the E370, and that remains true on the secondary market. However, the price differential on the used market is much closer than their respective MSRPs, as the E370 can be purchased for well under 50% of the original retail cost. The price difference on my units, both purchased used within a week of one another, was $100. The size, however, cannot change, and in that regard the 4VOX has the E370 soundly beat. At 29hp the 4VOX is still large (and odd hp ), but it’s dwarfed by the massive 54hp E370. It’s the massive size, however, that makes the E370 such a pleasure to wiggle.
Once mixed to mono in the Atomosynth Transmon, the 4VOX chords went through the venerable Industrial Music Electronics Malgorithm MkII, a powerhouse FSU-type module with bit crushing, sample reduction, and various types of waveshaping available to have anything from subtly crunchy through completely mangled audio at the output. Using Malgorithm was an absolute treat. Most of the lo-fi effects I tend towards are of the vintage variety, tape sounds, record pops, etc, vs just slightly old sounding digital artifacting, so it was a different sort of experience. On any other day I likely would have chosen distortion in this role, but the day I started this patch I precipitously chose to go with a different kind of dirt. And it was perfect. I was still able to get some nasty distortion via the “Axis” waveshaper (whatever that does), with the bit crushing and sample reduction playing a slowly increasing role. It’s starts clean, then moves to understated digital artifacting, and finally waves of full blown destruction, ending clean once again. One aspect of Malgorithm I enjoyed was the interaction between input level and the waveshaping. It responds similarly to tube distortion circuits, where the harder you drive the input, the more distortion there will be ranging from just barely there to outright obliteration. Each of these waveshaping circuits has three different levels, red, orange, and green, and all of them have their own character. These waveshapers can even interact with each other for nuking your audio from orbit if that’s what you want. I rode faders on the very awesome Michigan Synth Works XVI to control both the input level as well as the wet/dry mix in order to provide a performative aspect to this patch. Both the bit crushing and Nyquist parameters were modulated by the Addac506 Stochastic Function Generator, with a fairly wide range of both rise and fall times between medium and long. Each of the parameters were set to moderate crunchiness with the knobs, with their modulation moving towards a full-resolution signal. This created an absolutely amazing effect from the sound of dying batteries to the fabric of the universe being unzipped and sewn back together. I would highly recommend Malgorithm to anyone, but you’d have to find one first.
Once through Malgorithm and into the stereo matrix mixer, these now buzzy chords went to the Holocene Electronics Non-Linear Memory Machine, with a very light perfect fifth shimmer in the feedback loop. I initially went with a full octave shimmer, but decided against it as it was too prominent and spiraled too far out of control too quickly. This created a very subtle sheen on the chords that isn’t noticeable much of the time, but is a nice effect nonetheless. Feedback and Spread were both modulated by attenuated versions of the Average output from Swell Physics.4
The color tones of each chord were all sent to the mighty Frap Tools CUNSA, a quad filter extraordinaire, and pinged in a pair of Rabid Elephant Natural Gates. Though I was tempted to use the simple sine waves from each LPF output, I later decided to use the HPF output as a means of each oscillator frequency modulating itself in order to add some harmonics, which worked a treat. In retrospect, I could have simplified the patch significantly had I pinged CUNSA itself instead of running the output to Natural Gate, but I chose the Natural Gate route because Natural Gate.
Using a patch technique I’ve used often, the gates that pinged the Natural Gates were created by running the four waves from Swell Physics into the Nonlinearcircuits Numberwang. But rather than simply choosing four gate outputs, I ran several Stackcables so that each strike input on the Natural Gates were each derived from three Numberwang outputs. This filled in space much better. The notes are still sparse, but they’re triggered at a much better pace using three gates each rather than just one. These notes fill out chords in interesting ways. They’re very short, but combined with delay and reverb, those colors hang around long enough to create intrigue in the overall sound without being intrusive.
These notes were sent to what is becoming one of my favorite delays, the Chase Bliss Audio Reverse Mode C, a re-imagining of one of the modes on the legendary Empress Effects Superdelay. Although it certainly does standard stereo delay stuff, it excels at being a quirky sort of delay, able to output normal delays, reverse delays, and octave up reverse delays, by themselves, or in a mix. Mixing delays creates a beautiful sound space of echoes bouncing all around the stereo field, at different speeds and octaves, which is an incredible aural treat. I haven’t yet learned to properly modulate the Reverse Mode C, but that’s a function of not having a firm grasp on midi. As I figure that out, things ought to get very interesting, with different sorts of delays fading in and out in very creative ways.
The last synthesized voice in this patch is the Good and Evil Dradds as an effects send, sending both the chords and ornamental color notes for some granular action. The Dradd(s) outputs went to separate EF-X2 tape echoes with different settings. Ever since getting a second Dradd, I’ve been infatuated by what I can do with them, and this patch may be the best result yet. Both were set to Tape mode with similar P2, but different P1 knob positions, with the P1 parameter on both being modulated by an attenuated version of the Average output on Swell Physics. The Dradds, in some ways, steal the show. They create all sorts of movement in the stereo field and fill the space between chords and color notes in ways that keep the piece from becoming still. They’re the wake left after a large swell passes by. The bio-luminescence after a crashing wave.
The spoken voice is a set of three samples that were triggered in Koala on the iPad. Triggers emanated from the gate outputs on Swell Physics combined in the new Nonlinearcircuits Gator, sent to the Joranalogue Step 8 and then the Befaco CV Thing and converted to midi notes that were sent to trigger Koala samples on the iPad. It took me a while to figure this one out, though it worked exactly how I envisioned. Gates from Swell Physics were combined in Gator, which triggered Step 8. Each of the first three steps sent its individual gate output to a different CV Thing input. This ensured that the three samples were always triggered in the correct order. The samples themselves were then sent to a new collaborative delay plugin, Moon Echo, by AudioThing and Hainbach.. Moon Echo is a modeled simulation of bouncing sound off the moon, and has a very distinct character. The delay was set to fully wet, and has a delay of about 2.5sec, though that changes depending on the day. The moon is not at a fixed distance from the earth, and the plugin reflects that. By “pinging” the moon upon startup, you will get the current distance to the moon, and a new delay time down to five decimal points (1/100,000 of a second). Fucking cool.
One thing I did differently with this patch paid off high dividends, and will absolutely become a staple in my recordings. I’ve been patching for a few years, but am still an absolute novice at standard studio stuff. Mixing, EQ, compression, and everything else in that sphere evades me. I’ve used some very basic EQ in the past, but really only on the final output, which, as I’ve discovered has several drawbacks. This patch was the first I’ve ever recorded using EQ, the highly regarded Toneboosters TB Equalizer 4, on individual channels as they were being recorded. The chords, ornamentals, and reverb send received EQ that greatly improved the sound quality, even if it could still be better. I did, however, neglect to put EQ on the Dradds, which proved to be a mistake, as there is a very occasional pitch that pierces through in what can’t be far from dog whistle frequencies. It’s not eardrum busting, but I can hear it, and it annoys me. I didn’t catch that behavior when recording, and never EQ’d it out. That said, it was also the first time I’ve recorded a modular patch in separate multi-tracks, including the chords, ornamentals, Dradds, spoken voice, reverb return, and the mixed stereo signal (presented here). I can go back and make changes or additions should that be something I want to do, or send the parts to someone else for mixing and mastering should I ever choose to release it.
Overall I’m very pleased with this patch. It was originally composed in a different key and completely different chord progression, and for a special group of online friends. The chord progression I used in this recording wasn’t composed, as such. At least not by me. I asked ChatGPT for a “sad progression, yet with a sense of hope.”5 I asked for it to be more sad, and it changed key from Amin to Dmin, and ended in a non-diatonic chord (DMaj), which I found a wonderful “choice.” Then, as a means to test the Pianist, I asked for several chord extensions and inversions, and ChatGPT complied, giving us what we have in the recording.

I studied music performance in college, and have a decent grasp on music theory. The last 30 years, however, have pared that knowledge down to basics. I’m certainly no expert, but I can read chord charts and identify chord notes, even if I have to think for a second. ↩︎
The Humble Audio Quad Operator I purchased did not have the latest firmware update, and the internal VCAs all bled badly. I was unable to install the latest firmware with a modern Mac. I was fortunate to have an older one available to me that I was able to use. ↩︎
There are no fewer than seven modulation points in the patch that are all modulated by an attenuated version of the Average output from Swell Physics. ↩︎

Now that I have a few of the requisite cables to get my Make Noise synth back in playing shape, I decided to run a quick test of a couple of modules in the support Pod to make sure they would fit well in this system. My first intention was to make this a Make Noise only zone, which it may well still become, but I also wanted to integrate a small bit of gear that I thought might fit well with the Make Noise system comprised of a 4-Zone CV Bus Case and the0–Series. This small 48hp support case isn’t anything special. A couple of Knob Farm Ferry Send/Return modules for interfacing with a few pedals, a couple of blanks that will be replaced by either VCAs or attenuators to condition hot audio, and since I wanted my recording setup for this synth as close as I could get to Subsystems, I added an Expert Sleepers ES-10 ADAT Interface that connects to my audio interface and allows for easy multitrack recording.
But one not-Make-Noise module that is also in the support case is a noisy reverb that I’ve had for about a year, the Maneco Labs Otterley, but didn’t use it much because it’s pretty noisy at anything past about nine o’clock on the reverb dial. The controls are quirky, with no real wet/dry control, but a Reverb 1 control that affects every aspect from the wet/dry mix, to size, to decay, a Reverb 2 control that isn’t really a reverb at all, but a sort of reverse granular delay, and a Feedback knob for Reverb 2. It also has a set of secondary control trim knobs for the granular engine. I don’t think Otterley sold well, I bought mine on a very deep discount, and I’m pretty sure it’s been discontinued. I’ve never really seen much about it, and my initial observations over the last year weren’t necessarily that great. I figured it’s just not very good.
But for some reason I can’t wholly explain, I kept it. I’m certainly not afraid to move gear I don’t gel with quickly. My Reverb shop is fairly active, with almost always something for sale. I move a lot of gear out, and this module should have been something I sold long ago for real lack of use. But something about it interested me. It was noisier than I’d like, but something about that noise was interesting, so I held on to it hoping that one day I might have a spot for it. And what’s more is that generally speaking, I don’t like reverb modules because, in my experience, modulating reverb hasn’t been productive. Reverb is more of a set-and-forget effect, and not something that benefits from modulation outside of a few edge cases for sound design. It’s precisely why I favor reverb pedals, and use three of them with Subsystems, while having zero racked reverbs outside of those found in modules like the Mutable Instruments Clouds and Beads. That I decided to keep the Otterley when you consider that I don’t like Eurorack reverbs, didn’t particularly care for this one in specific, and have the tendency to quickly sell modules I don’t like, really baffles me. But once I knew I’d have a dedicated space for a Make Noise synth, particularly after my first encounters with a Strega, I knew the Otterley would be perfect. At least paired with the Make Noise synth is a spot where it has a chance to succeed, rather than a spot where it was sure to fail. It seemed to me that at worst, the noise would be indistinguishable from, or masked by the noisy nature of the Strega. In a better scenario that noise could add to the Strega in a positive way. And although I don’t know yet my ultimate determination, I can say that the noise of this really weird reverb is at least masked by the Strega, and Reverb 1 adds a very interesting stereo field without being terribly noticeable. The size and decay can become very long, carrying on seemingly infinitely, or at least until I got tired of waiting for the tail to resolve and turned down the knob.
I’m still yet not at all decided whether I like Reverb 2, the reverse granular delay. I’m sure that it’s highly dependent on the material fed to it, but I’m not sure that I understand it when used in context of a standard Strega drone. It seemed most interesting when pitched up an octave or two, but there’s still a whole lot of testing to do with this section. It’s possible that it’s simply not all that useful, though if not, it doesn’t bode well for the AC Noises Ricorda that is currently the system’s reverb pedal and has similar granular controls (although not only in reverse).
I very much look forward to further exploring the Otterley.
A Note: The faceplate of the Otterley is quite interesting. Not simply the design, but that the design is on an upraised section atop a normal faceplate, giving it texture and depth. It’s really cool.
