I recently got a project that was recorded in a DAW (BPM unknown). In GB, I can align/sync the GB click and BPM to around the first 16 measures, but the song seems to drift from the GB click. Is there a way to quantize a prerecorded track?

Hi Chance123 - Assuming you're talking about an audio track, if the drift doesn't get too far off the beat, you could try quantizing the audio by enabling Flex -- check out the video below, he gets into quantizing audio starting at around two minutes in.. [You might need to break up the track into multiple Regions if the drift gets further off later in the song] You could also check out the next video in that same course, on syncing to GB's Groove Track.. [If you find yourself having to do this kind if thing a lot you might want to consider a bump up to Logic, whose Smart Tempo feature is designed to deal with this]
