I have a lead vocal track on a song that I copied, and added to another track to extract the chorus parts only. That done, I copied the chorus track and pasted it into the next track down so that I could pan the chorus parts right and left with the lead vocal in the middle. What I got from the second chorus track (an unedited copy of the first) was a "chipmunk" vocal. The chorus tracks are identical. There are no differences in either track other than how they sound. What have I done wrong?

Thanks in advance for any help and suggestions.
Best wishes,


Keep on Rockin'
