Doepfer

I was playing around with the Oddity softsynth the other day and got
thinking--I've got more than enough oscillators on my modular (4) to
make some amazing duophonic sounds.

How would I go about this?  I've got the basic Doepfer MIDI-CV
converter and an M-Audio Axiom controller...obviously the problem
would be figuring out how to assign each of the two voices.  Can I do
this with my current equipment?
