I set up four similar patches, each with two of the same Low Pass Gates module, four different makes. Each patch looks like: S&H -> Oscillator FM; Oscillator pulse out -> LPG input; Envelope Generator -> LPG CV input; LPG output > Mixer.
Eight triggers, generated by Pithoprakta, are used to trigger the S&H that picks a new pitch for the oscillator at the same time the EG is triggered. It’s eight-voice polyphony (but we’ll listen to two at at time). Pithoprakta is clocked by the Ultra Random Analog, which self-modulates, creating irregular notes.
In addition, six of the envelope generators are voltage-controlled and receive CV input from the six outputs of Just Friends.
The recording listens to about one minute of each of four patches. It’s not meant as a comparison, but more as a sampling of different low pass gate sounds.
