Here’s another Cold Mac patch idea:
Oscillator -> Optomix Ch 1
Optomix sum out -> Cold Mac crease
Cold Mac crease -> Optomix Ch 2
Cold Mac crease -> listen
This patch can be harmonic, noisy or chaotic, depending on how the Optomix parameters are set. If you leave out the input entirely, then Cold Mac and Optomix can be an oscillator all by themselves.
You don’t have to use Optomix, any low pass filter will do. Actually you don’t need to use Cold Mac either. Here’s a demo of some possibilities with a few different combinations of modules:
