Yes, I'm surprised.
Only in PRO.
But you can via Generic Midi Device (Midi Learn Funtion) the Transport Window reassign.
I have tested this before, and had only problems with the Transport Buttons, because they dont send a Midi Signal. with the other Pads or Knobs no problem.
Perhaps its because the MMC Funtion.
But with the other solution its no problem, but you need the Pro Version.
