I hope this is OK to say, but perhaps a different kind of synth would suit
you. Polyphony can be achieved with a modular synthesizer, but it is
expensive and a bit of a pain to set up. There are several polyphonic
analog keyboard synths with exactly the kind of control you are looking
for-- multiple full-fledged voices with common control over the parameters
such as ADSRs and filters for each voice. They are engineered for real-time
polyphonic playing so it is already set up in the way it needs to be and
does not require the work that a modular does. It also does not take
several huge cases to hold it together. In my opinion if you want to play
polyphonic keyboards, this is a better route than modular which is better
suited to monophonic playing and sequencing, and then recording and layering
afterwords.

As for which kind of synth to get, the Dave Smith Instruments Prophet 08 and
Poly Evolver are still in production. You can also look to something
vintage like Roland Juno 6. Also the Alesis Andromeda was recently
discontinued but can still be found. I personally use an Ensoniq ESQ-1 for
polyphonic performance which is a nice digital/analog hybrid and can be
found for cheap.

Best,
Monroe
