Just today my band was recording using Acid Pro 6.0. The drum tracks are already laid down and were attempting to record the guitar over it. The problem we are having is that when the guitar is recorded and then played back it seems way out of time with the drums. But the weird part is that just before it started doing this it was fine. We recorded the guitar part to the whole song, played it back, and it was in time. Our setup is a 12 channel mixer going into a sound card on a PC. Like I said it was working just before it started doing this, literally within a couple minutes. Also we recorded a demo a few months back the same way and it was completely fine. Does anyone know whats going on?
