Thanks for the reply -- your help is definitely appreciated.

There was no switch to an external digital clock... not that I know of, at least. I recorded at a sample rate of 44.1 kHz. The pitch is up/faster.

To my knowledge, I never opened a session with a different device in the audio engine. I should mention that I have a PreSonus Faderport, and that I was playing around with the punch feature on that for the first time. I don't think that would've caused it, but maybe it did...

I opened the sessions again this morning, and they're all back to normal. It's the weirdest thing. Even though they're all fixed, it'd be good to know what caused that to happen in the first place.

Thanks again for your help.
