Good to see more demos of polyAT emerging out of the shadows. As this becomes a more common feature, hopefully we'll hear more creative uses of it beyond CS80 immitations.
Sorry, but the M can’t handle polyphonic aftertouch. Channel pressure and polyphonic aftertouch are different MIDI event types. The M receives both event types as well as the Blofeld for example. BUT. Both can‘t resolve the polyphony and process both events as channel pressure. What you hear in this video is channel pressure, not PA, since the M can’t process PA as PA. You can check this e.g. with max. amount on cutoff.
not sure what you're trying to explain but the M definitely processes PA and that is what you are hearing. In my book channel aftertouch is monophonic aftertouch on a single midi channel i.e. the pressure value of whatever key pressed last is the value that becomes the same source for modulation for every voice. wirth PA each voice produces/listens to it's own voice number aftertouch value which is what the M does perfectly.
