Great info in this thread. Thank you for posting.
I just discovered that when you record the output from the chord pads played live, the resulting MIDI also gets split into channels 1 to 4, which you can see if you set the MIDI editor to color by channel. Oddly, when you drag a chord from the chord pad to your MIDI track, the notes do not get split this way. Or if you create MIDI from chord events, the output is also just on one channel.
This seems a little quirky to me but possibly useful if you don’t mind playing in from the chord pads.
