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.
