Cicadas Arise

It happens here every 17 years. Brood XIV emerges from their long underground slumber and takes to the trees. During this time, perhaps over a trillion cicadas will emerge over the course of 4-5 weeks throughout East Tennessee, the eastern half of Kentucky, and small bits of far western North Carolina, Virginia, West Virginia, and southeastern Ohio.

I was here during their last emergence in 2008, my first time experiencing periodical cicadas, and at times it was a complete caucauphony. There were times when I felt as if the sound was coming from inside my head. The volume can get so loud that being indoors was barely a respite. That what happens when perhaps two million of them are on my property in the Kentucky Bluegrass. For these next several weeks the cicadas of Brood XIV, the children of the last generation I saw nearly two decades ago, will be ever present, serenading the world with their song. But their collective song isn’t monotone or at a static level. It pulses. It has a natural ebb and flow that rises and falls in what can only be described as a most beautiful chaos.

I recorded a short snippet earlier this afternoon, about 22 seconds worth, so that I might put them through the synth. I’m sure I’ll get other recordings, especially as they get louder, but I wanted something to do today.

I can’t really remember this patch very well. It was a very stream of consciousness-like affair, with lots of changes and adjustments along the way. I’ll write what I remember as clearly as I can, but this will not be a comprehensive breakdown.

I recorded the cicada sample onto the Miso Modular Cornflakes buffer. After recording, I let it playback continuously in a loop, while heavily modulating every parameter with four outputs from The Hypster, via Let’s Splosh. Speed, Pitch, Grain Size, Diffuse, Position, and Length all received healthy doses of mixed, rectified, and attenuated chaos, while Harmonics and Distribute received modulation from an inverted sequence slowly running in the Verbos Voltage Multistage, and clocked by a single gate output from the Nonlinearcircuits Numberwang. Numberwang was fed from four outputs of Let’s Splosh. These were the last four available outputs from Let’s Splosh (this marks the first time I’ve used all 16 outputs in a single patch), so the movement they created isn’t very much. Only four of the 16 gates were ever high in Numberwang using these signals, but it created just enough movement to keep the sequence moving. If I had to make a comment, I’d say that I severely overmodulated Cornflakes. There’s a lot of swirl, and what sounds like filtered noise. The result isn’t bad, per sé, but there are many things I’d ease up on were I to record this patch again.

This wonderful swarm of granulated cicada-song was sent to the Frap Tools CUNSA for heavily modulated Bandpass filtering (introduced at ~ 00:50), using Sapel’s smooth random outputs to modulate the center frequency, along with two Falistri functions performing AM at audiorate in CUNSA’s built-in VCAs. This filtering created a lot of stereo movement in the best kind of way, and the AM from Falistri gave it an even more fluttery sound, mimicking the cicadas’ awkward flight amongst the trees.

Both the Cornflakes and CUNSA outputs were sent to the Industrial Music Electronics Malgorithm MkII for some lightly modulated bit and sample reduction, along with the smallest bit of waveshaping via the Green setting of the third button (introduced at ~01:35). It’s an effect, in this patch at least, that is subtle. It’s hard to pick out in context, but when it was not there it was quite noticeable.

The sub bass (introduced at ~02:10) was created with a Verbos Haronic Oscillator’s saw output through Amp & Tone, which was amplitude modulated by the Harmonic Oscillator’s mix output. Different harmonics (8, 7, and 6) rose and fell via cascading triangle functions from the Polyphonic Envelope, which created subtle pitch changes in the drone as it took on the pitch of the higher harmonics via unattenuated AM. The frequency cutoff was modulated with one of the cascading envelopes from Polyphonic Envelope, first lightly to create subtle movement in the timbre of the drone, then more heavily, and with high resonance, to create a beautiful, if dark, background for the cicada song, with streaming harmonics from the saw wave echoing in the stereo field. The filter output was sent to the Multi-Delay Processor, with the dry signal from MDP’s output going straight to the mixer, while four separate tap outputs were patched to Scan & Pan, hard panned, two taps to the left and two to the right, and mixed in the Addac System Addac814 6×6 Stereo Matrix Mixer.

I tried mightily to use the Rossum Electro-Music Panharmonium in this patch, but I simply couldn’t get anything at all that I liked. I ran into, and quickly lost, a couple of sweet spots, but I didn’t have the discipline to keep the knobs still. The cicadas create a highly detuned chorus as it is, and swirling dissonance through the Panharmonium was a huge mess. There were a couple of times when I used a feedback path in the matrix mixer that created a beautiful, deep bed of pads, but it was quickly gone. I suspect that much faster analysis times would likely help with this sort of input material.

A Dark Drone: First Patch With Sibilla

I was recently afflicted with a particularly bad case of GAS. During this latest bout, I hurredly purchased the drone specialist module, Sibilla by Clatters Machines. I didn’t need another drone machine, but after a couple of recent subsystem rearrangements, I had 10hp to fill in my Stereophonic Black Subsystem, and within a couple of YouTube demos jumped at the Sibilla. I don’t like GAS, and I know that it can be unhealthy, but it sometimes (oftentimes?) gets the best of me.

Despite my knowing it wasn’t a particularly wise purchase, I still thought that Sibilla could produce something nice. Had I doubted it, I wouldn’t have succumbed to GAS, at least not for this particular module. I had meant to use it in my recent Piano Mist patch. I had it patched up but never turned it up in the mixer because I was so enthralled with what I had in the Piano. So today I decided to start with Sibilla and see where it could go.

One of the reasons why I bought Sibilla was because I have a difficult time resisting additive oscillators. Although Sibilla isn’t anything resembling a standard oscillator, it does use additive synthesis as a big part of its process. Along with multiple delay lines and a fixed low pass filter (with adjustable resonance), Sibilla adds harmonics using different waveforms that are differently phased to help create a bed of complex moving textures. Naturally I wanted to emphasize those harmonics to create not only movement, but a sense of chordal change.

My initial experimentation was simply playing the Rise and Fall knobs, which was very cool. Improvising isn’t something I do very much, and I greatly enjoyed it. I even tried using the Doepfer A-198 Trautonium Ribbon Controller, but I decided to keep this sketch as more of a drone with full harmonic changes, not a part of a drone while using its harmonics as an improvised solo. So in order to create those chord-like changes, I reached for 2 of my favorite things: chaos and sample and hold.

I ran one of the outputs from a patch programmed Joranalogue Orbit 3 to the Joranalogue Step 8’s input. Step 8 functions as a really large Sample and Hold, with each step running as an attenuator. The trigger for each step comes from the Rise gate of a modulated looping Contour 1. The steps are not regularly triggered, so there’s nothing to time. The Step 8 samples the chaos signal, attenuates it depending on the slider position, and sends out that voltage to the Fall input. Each cycle is in continuous flux, creating movement, but not regular movement.

Joranalogue’s Orbit 3 is an unsung hero of chaos modulation. Nonlinearcircuits dominates the chaos landscape in Eurorack, and other forms of chaos generation are often overlooked in light of NLC’s vast catalogue and strong pedigree as the source for chaos in modular synthesis. But Orbit 3 has some distinct features that make it a compelling competitor. It’s controllable in a way that NLC’s chaos generally isn’t. Orbit 3 has full frequency control, a reset, and you can control the position of both attractors. I’ve been able to consistently get compelling low frequency waveforms that are interesting and easily tweakable. I don’t always want overarching control over chaos signals and how they go about their business, but when I do I patch Orbit 3.

The Audio Path

The audio path of this patch is fairly simple:

  • The L/R audio outputs of Sibilla > Bizarre Jezabel Pkhia stereo multimode filter (LP out) > Worng Vertex stereo VCA for a bit of volume manipulation > Channel 4 of the AI Synthesis 018 Stereo Matrix Mixer.
  • The audio is then sent from Output 1 > Miso Cornflakes.
  • Cornflakes > Ch 1 input of the matrix mixer to be mixed with the dry drone signal.
  • The mixed drone and granular processing is output from Ch 4 of the matrix mixer to my final mixer.
  • A send to the Vongon Ultrasheer for some reverb and vibrato, and we’re done.

I didn’t particularly need to send the output of Sibilla through another filter, it has a low pass filter of its own, but I wanted to create more movement per channel. I initially wanted to use Pkhia’s Band Pass outputs, but that didn’t really work, so decided to use the LP outputs with the filter set initially almost completely wide open. With some chaos modulation of the filter cutoff in each channel I was able to get slow, unpredictable appearance and disappearance of some harmonics which created lots of subtle, yet interesting, effects throughout.

Cornflakes is set to a constant pitch of +2 octaves, with its position, grain size, grain length, diffusion and speed being heavily modulated by chaos. This effect creates the slightly detuned shimmer on top of the drone, and heightens suspense as the patch moves along, finally releasing some of that tension before the drone fades away.

The reverb and vibrato is the exceedingly good Vongon Ultrasheer. The reverb portion is set with a long tail and no pre-delay. The tails also are set to favor higher frequencies to help avoid mud in the lower frequencies. Sibilla has 4 separate delay lines, so the lower frequencies aren’t without its own sort of reverb. I just didn’t need them delayed and diffused even more. Although I didn’t notice it while recording, there is a bit too much vibrato. It’s not distracting my any means, but it’s a bit too much in depth and speed, and it is noticeable in a way I rather it weren’t; like a shade too much syrup on your waffles.

The Control Path

If the audio path is simple enough, the control path is anything but. The heart of the modulation in this patch is chaos generated by a patch programmed Orbit 3. More chaos is used from NLC’s The Hypster. Slow chaos affects nearly every parameter of the patch, with the Auza Wave Packets in its debut role in my synth on 3 Cornflakes modulation targets.

Sibilla doesn’t have every parameter being modulated, but there is still a fair amount of modulation. Orbit 3 is modulating the Rising harmonics and resonance, while also supplying the signal for the Step 8 to do its sample and hold business.

Orbit 3 is also modulating the cutoff frequency for both sides of the Pkhia, the rate of the Rise and Fall on Contour 1, as well as self-modulating the EP+ and Distribution as a means to keep the signal ever-changing.

Step 8 provides the changing chords via its sample and hold functionality at the Scan output to Sibilla’s Fall input, triggered by the Fall gate of a constantly changing, looping envelope from Contour 1. The Analogue 3 output modulates the Distribute input on Cornflakes, with Analogue 5 modulating Orbit 3’s Distribution.

Contour 1 provides the stepping action for chord changes with its Fall output, as well as gating Cornflakes’ record functionality with its Rise gate output.

The Auza Wave Packets, a complex modulation source centered around various stages to create sophisticated wave types, made its first appearance in one of my patches. I’ve never used it before, and still need to learn lots of things about it, but it seems the possibilities are endless. In this patch, I used “The Unipolar Wave” (output 2) to modulate Cornflakes’ grain Size, “The Capsulated Oscillator” (output 4) for the Length, and “The Pure Oscillator” (output 5) for the Position. NLC’s The Hypster played a minor in rounding out modulating Cornflakes’ Speed and Diffuse parameters.

There are still a lot of details to work out with this patch. The modulation is largely not attenuated or scaled in any meaningful way. I’d probably try opening up the attenuation on the chaos signal used in the sample and hold to change chords. I’d also try and see if I couldn’t hone in Cornflakes to something a bit smoother. But overall I’m pleased with this first patch, and I look forward to doing special things with it.
