Hi,

I use my modular (Doepfer/Analogue Systems mix plus a few other bits) as a duophonic with separate and identical architecture for each voice. I use the Kenton Pro-2000 as a Midi-CV converter, with one channel set to the Lowest Note and one channel set to the Highest Note. I have just redesigned my whole synth and got new modules to achieve this more effectively (I now have 6 RS95s and a pair of RS110 VCFs plus a few other filters). It is very satisfying and I thoroughly recommend it.
