I've been looking around a bit and can't seem to pinpoint which Audio intereface would be ideal for laptop setup on the road? I've looked at a couple of Motus and like the Traveler. And I have looked at M-Audio products. Basically I am looking for a light weight 4 input or more bang for your buck type scenario. I'll be running Logic Pro mainly and would like the ability to record multiple real life instruments in rehearsal studio settings and such. Any and all help would be appreciated. Thanks in advance!
