I'm using Studio One 2 on a 2008 iMac with 12G RAM. I am also using the EXDrummer Toontrack plugin for drums. I have recorded three simple song ideas with either impact or EZDrummer for a basic drum track, and then 2 or 3 audio tracks (guitar/bass/vocal) I've set the song tempo manually on the transportbar for each song, and during the recording sessions, this all worked absolutely fine. I did a wav export of one of the tunes as well without issue.
I then came back to the songs a couple of days later, and all of them are playing too fast. The pitch is approximately a tone sharp, and the vocal sounds like the singer has taken helium. Does anyone have any ideas what might be wrong? Is there a global setting somewhere I'm missing?
Many thanks in advance,
