I don't know how I got in this mess. I didn't change sample rates or stretch anything intentionally and the vocal track is in good sync. I wonder if anyone has an idea. I'll most likely just do the guitars over, but I'd like to know for future reference what caused it and what the remedy is. Stuff like this keeps happening in Logic. Things will get way out of whack and I don't know if there is a bug or I accidentally hit some key or what. In the screen shot you can see a one bar repeating riff that steadily loses sync.
