Dual ADSR with separate controls for each envelope generator. Dual ADSR with controls shared between each envelope generator. Stripboard layout for core building blocks of a basic polyphonic build based on Polykit’s Pi Pico DCO. Could probably be squeezed into a 4-voice module without too much issue, lots of options for modding. Hopefully useful for… I posted a stripboard version of the polykit build - would definitely be scaleable, the bottom image on the link shows what you’d need to get two voices going (except for the vca and mixer board, which shows what you’d need for 6 voices). There’s no filter here as I just mixed the voices down and passed to a single ms20 filter, which is a limitation. I later did a version for my brother with polyphonic filters too using AS3350 chips, but I did that on pcb. Would be simple enough to use one of the AS filter chips and build a stripboard for each, though you’d also need to double up on the envelope generators. --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/polyphonic-synths/7399)._
