Hey!
If you're talking about just one isolated beat that hit wrong,What I did was do the math using the waveform screen and took some silence from one place and moved it, or whatever the situation reuired. If you're talking about the whole song, I would suggest A) if it's a loop, edit one correctly and copy it B) if not...sorry, record the track over 'cause it would be a real pain to try an edit it all out IMHO.
