4 oscillators using 3 MIDI channels (2,3 and 4 – as I was using a Keystep and MIDI 1 was used for drums).

1 and 2 have their own VCA and ADSR.
3 and 4 share a VCA and ADSR

1 and 2 are mixed before a filter then reverb
3 and 4 are mixed before the VCA then filtered and delayed

2 has PWM
4 has PWM
4 also has CV detune so it’s not exact with 3

I use it with 1 and 2 playing bass/chords and 3 and 4 play together (like a single dual osc mono synth).

CV inputs used to modulate
1. 3+4 level
2. 3+4 filter
3. 1+2 filter
4. level of 2
