MOTM

It takes 2 elements:

a) A MIDI-to-CV converter that can either handle 2 MIDI channels (ie a keyboard split) like the
Pro-2000. Or, a MIDI-to-CV converter that that assign multiple notes from 1 incoming MIDI channel
(Encore Expressionist).

b) multiple 'sets' of modules. A 'voice' may be 2 VCOs, a VCF, 2 EGs and a VCA. For a 4-voice
system, you would have 4 duplicate sets of these.

At NAMM, we had Robert Rich's 38-module system running 7 independent voices all at once.
