When you are looking at a midi track in the matrix view, is there a way to hit a key and have the Hypereditor that shows MOD wheel (or sustain) come up? I know I should probably just save a window set....;)
Look up and assign a key command for "Autodefine".
That way, when your in the Matrix editor, you can hit your new Autodefine key command, and it will scroll through any CC controllers that have been written to that track.
