I have a fairly lo-fi recording setup consisting of a Behrenger mixer running into the audio input of my Mac Book Pro 2.33 GHz Duo 2 Core notebook. I have 2GB of memory. My issue is this: I was recording drums today and had 3 mics going into the mixer and the mixer slipstreaming those 3 mics down to one track in GarageBand. The drummer played everything totally in tempo (I kept an eye on the metronome the whole time!) but when we went to listen back to the take, it was completely out of sync with the rest of the track. Or, it would start out in sync and gradually get bad. Again, I watched the metronome while he was playing and he played everything into the DAW perfect. I've never had this problem when I record at home, only when I go over to his place to record. We had a similar problem the last time we had a session, but I quit out of the program and it cleared itself up. I tried doing that today and it didn't work. I also checked the load on the processor and it was never taxed above 56% of its capacity unless iStat isn't as accurate as I think it is. Anyone have any idea what the problem could be? Any help would be greatly appreciated! Oh yeah, and uh, first post.
