Here’s a patch diagram of how I did the chord changes in my latest patch, What Are We Even Doing Here?….
A quick explanation….
- The four waves from Swell Physics that control volume of the chords are all fed to four VCAs, as well as an analog comparator (Xaoc Devices Samara II).
- Samara II compares the signals and outputs the Maximum (AKA, Analog OR) voltage level of all four signals at any given moment.
- This signal is fed to a window comparator, (Compare 2), which generates a gate every time the Maximum signal goes below 0v.
- This gate goes to the Clock input on the NOH-Modular Pianist, which changes to the next chord in the sequence.
