I think that the ES has 3. Don't know how many on the rack. Prob 2, since it doesn't have pass-through terminals. Hmmm, or does it. I don't think the classic rack even had USB. Anyway, I don't guess I'm help on this. I've always owned the boards, not the racks. The boards are great for a blind guy because of all of the dedicated controls. That isn't there on the rack.

Hi list members, i'd like to know if I'm using my motif es through the u s b port, how many instances of the motif es should i have? P.S. Would this also apply to the motif classic rack?
