I spent a lot of time setting the panning on all my drum parts in Session Drummer, and when done I bounced them all to their own tracks. Long story short, I screwed up and all my panning is backwards. Rather than go back and re-bounce everything, is there a way to reverse the L and R channels on a stereo audio clip so that what was left is now right and vice versa?

• Channel Tools is a plug-in based, non-destructive option.
• Process > Apply > Gain is a destructive option. Select only left channel in the right channel, and only right channel in the left channel.

If I may ask, you say you bounced them all to their own tracks? Why are they stereo then? I would expect you to bounce them all to mono tracks (as with a real mic'd drumkit) and do the panning after the fact. I realize that doesn't help you now but it seems Craig already has you covered. Perhaps an option to think about for next time, or is there a reason to do it your way that I'm missing?

Yay, any easy solution! Thanks Craig!
 
@Sanderxpander I wasn't thinking that hard about it when I bounced them. I had other confusing fish to fry at the time. This project was ten years old and I'm redoing it now, and there was a lot about it where I had no idea why I did it this or that way. I was just trying to get through it. 
 
Actually, after I posted my question though, lying in bed, I realized that I could just make every track mono and pan it again. Craig's solution was great though.
