I’ve just recorded myself playing the rhythm guitar part over an MP3 backing track of Highway To Hell.
During recording it sounded perfect and my guitar sounded totally in sync/time. At the end of recording however when I play the thing back my guitar and the backing are in sync for say 5 seconds and then the guitar part gradually comes before the backing track (as it were).
I’m recording via Line In and have two stereo tracks - the MP3 in one and my guitar in the other.
Any ideas what’s up with it??
