I hook up my S88 MK3 to Ableton via my computer USB but was also hoping to connect an external keyboard to the controller for purpose of using S88 Mk3 sustain pedal to work with my external keyboard via midi cable. My Novation keyboard allows this but so far, I only have read where it's either USB or Midi cable out of the S88 Mk3. Can someone help confirm this situation and if any eventual fix from NI? As a controller keyboard, without this ability, it seems limited.
