Patch Examples
- Patch 1: Simple waveform to In, Sum out to mixer, play with knobs.
- Patch 2: Complex sound (drums/melody) to In, adjust drives for creative distortion.
- Patch 3: Oscillator to In, envelope/LFO to All CV for multiband distortion with VCA control.
Power Connection
- Align the ribbon cable so the red stripe is on the -12V side of both the module and power board.
- Double check proper orientation before powering on.
