GarageBand - tracks are a step or so lower in pitch

I am currently trying to record using GarageBand, but when I play back the tracks, they are a step or so lower in pitch. This has never happened before and I can't figure out how to fix it. Anyone know what's going on?

Thanks!

It's probably your buffersize, make the buffersize the same as digicore.
That should solve the issue.

Make sure the sample rate is set to 44100.0Hz or 44.1 KHz.

That worked. Thank you!

Just don't forget to visit sometimes;D

Just curious... is this GarageBand '08 or '09?

Wasn't sure how to change buffer size, etc when I encountered this problem. The solution can be found here for GB '11: GarageBand '11: Set the audio resolution
