From a quick experiment: the default preset chords usually also map Knob A to Filt Freq via the cords menu. By removing that cord mapping (on each layer), MIDI A will no longer control cutoff, EVEN if cc 74 is assigned to MIDI A in the controllers menu. Incoming cc74 is not by default recognized by the CS (confirmed in the manual - MIDI chart). However, if you re-assign midi A to cc74 and re-establish the relevant cord, then the CS WILL recognize incoming cc74.

CCs 7 and 10 (Vol/Pan), however are by default recognized, so by assigning knob A to cc 7 in the controllers menu works, and the CS will also recognize this incoming cc, independent of any cords.

So, if a cc is not by default recognized by the CS, you need to assign that CC to a knob and further map that to a cord to tell that CC what to do...???

Is there a more direct way? What if I want to map an incoming cc to, say LFO rate? MIDI CCs are not modulation sources in the matrix....

For example CC74 might be Filter Cutoff Frequency and CC71 might be Amount of Filter Resonance and you cannot change that. However, with the P2k synth architecture, to can assign different CCs to different knobs (MidiA -> MidiP on 16-controller systems) and then use those CCs (via MidiA -> MidiP as patchcord sources) to control whatever destinations you want.

So if you change MidiA from CC74 to CC16 and MidiB from CC71 to CC17, ONLY CC16 and CC17 will affect Cutoff and Resonance, respectively. [Actually, now that I think about it, I believe I can change CC assignments in my M-GS64 via sysex commands; so maybe they're not really hard-coded, just "difficult-coded."]
