Enlightening thread. I had no idea that the MP-201 was being phased out. I've researched it obsessively, always thought that the issues linked by imekat above were largely addressed in Version 2, and come this_close to buying one on many occasions. Largely, it would be to consolidate some functions of my current setup, with a milder interest in converting the CV output to control other pedals. Those EG parameters are enticing.
My combination has a Lexicon MPX-1 for the control stuff [tempo, LFOs, envelopes, S&H, etc.], followed by a FCB-1010 for expression pedal(s), patch changes, static CC values, etc. That's the head of the MIDI stream; distributed to the various audio processors downstream. The MPX-1 (MIDI-channelized) controller information merges with all of the (MIDI-channelized) per-switch functions via the FCB-1010's Soft THRU setup.
Something like that isn't going to 'feed" those CV devices of yours, but I point out my routing to give you some ideas about alternative options over MIDI. The 5 simultaneous program changes cover my pedalboard, and the programmable CC values are perfect for 'Factor pedals. I use the two MIDI 'expression' pedals in a more global sense, as the individual 'boxes all have their 'local' expression pedals, switches, and / or auxiliary switches.
There's more to it on the rack than that {MIDI rack effects, MIDI router, sequencer, keyboard-specific routings], but that's not pertinent here. I'd be interested in your take (or anyone else's) on the CV applications of the 'Factor pedals. Only a passing mention is given in the UM. Maybe we can kick around some schematics on how to design 'safe' connections to the various voltage ranges out there. 0-3V always struck me as odd, but no stranger than – say – a Pigtronix Philosopher King using a 2-12VDC range.
