Hi again!
Hmm, I wonder if this really true...? and please correct me, if I'm wrong.
Spark2 (GUI) receives all MIDI commands (like CC, Midi Notes, Patch Changes) from a hardware controller on all 16 MIDI channels at once
(not on a certain one). So it seems to me, we won't be able to send the same MIDI command on different channels to manipulate
different things.
Cheers
