I configured my GarageBand to use an MBox a while back, but I didn't really try to use it until last night (after the GB 1.1 update). My input levels were all low during recording, and when I finished recording the sound compressed to double-time and the levels went way high. I had no problems doing the exact same thing in Pro Tools. Is the GB update not compatible? I checked the Audio MIDI Setup for options, but there weren't any.
