I wanted to be able to use all three oscillators independently so I chose which controls and which inputs should affect all or be independent per VCO. I chose PWM and Width to affect all three VCOs to minimize panel space. The width control and PWM inputs are simply paralleled to each VCO.
I chose 1V/Oct and FM to be affect each VCO independently but normallized the input jacks so they could affect all three together. I also eliminated Detune for VCO1.
Since the input modulation of vibrato and portamento can be bypassed for VCO2 and VCO3 through their separate 1V/Oct input, I needed to make sure the gain through the modulation circuitry was 1X, so I used 0.1% resistors for U11B and U12A
I did add a mix output and independent level controls for each VCO. I use that feature a lot.
The wiring diagram is shown on my page as well as the details of my modifications. I remember the link/track conversation but am thinking that was for the Polymoog Resonator module. I don't exactly recall now.
