Catophonator is a crossover between Cacophonator and MFOS WSG with some additional functions. It is based on 40106 hex inverting Schmitt trigger.
- 2 generators - OSC3 and OSC4 run always in audio range,
- 2 generators - OSC1 and OSC2 can run as audio range generators or LFOs, gating (or not) OSC3 and OSC4,
- 2 generators - OSC5 and OSC6 are sucking current, which result in 40106 abnormal operation,
- output from OSC1 to 4 can be mixed via resistor or diode circuit,
- OSC1 can be gated with external (f.e. audio) signal (unfortunately it doesn’t work very well).
Controls:
- OSC1 - OSC6 tuning pot,
- STARVE control (red knob),
- OUTPURR level,
- OSC3 and 4 gating on/off switch,
- OSC1 and 2 range switch,
- mixing mode (resistor / diode) switch,
- OSC1 gating from external source switch,
- power on/off switch,
- power on monostable button (the red one).
