With Overbridge & Ableton: it seems like sometimes he is “pitch bending” the a4 (not like pitch bend on a midi keyboard) but more like bending with + and - on a DJ CD player (to make it back in sync), or like what you do with vinyls to sync it again. So it does it with all four tracks of the A4. Its a syncing problem I guess.
Anyone know why?
Settings overbridge = CLOCK (transport + tempo)
Settings A4: input from MIDI + USB
