What reason is there to disable certain controllers when in the system menu?
I don't care about the synth controls that much, but could the octave shift buttons and wheels be working normally please?
I would like to use PRO 3 to regularly play other synths as well, which is best done by being in the MIDI system menu, so that I can change MIDI channel to the target synth. However it's a PITA that I must exist the menu if I need to shift keyboard octave.
