There are basically three approaches for polyphonic modulars with one
common aspect. The common aspect is a polyphonic keyboard.

The three approaches are:
1.) The Korg PS-Series type: identical architecture for each voice. All
parameters are voltage controlled so you can patch these control
voltages. The approach is quite close to standard polyphonic
synthesizers. Also the Nord Modular use this kind of polyphony.

2.) The Oberheim SEM type. You have several identical architectured
voices, but individual parameter settings and patchpoints. You can use
either the A111-5 or the Doepfer Quad-xxx modules for it.

3.) Large modular systems, where you have enough modules of each kind
(sometimes not really identical) to patch several voices for a
polyphonic synth.

My A100 can do a basic type-3 synth:
four VCOs mixed 2x110, 2x111
four VCFs 120, 122, 101-1, 105
four VCAs
four ADSR
Quad LFO

I also have a Korg MonoPoly, which I will extend with an 135-2 and some
kind of eight VC-ADSRs. This one will be a mix of the type-1 and the type-2.
