Time stretching not syncing to bpm
This has been bugging me for a week, I take a sample that is a 4 bar loop with a bpm of 97 and I time stretch it to match song bpm at 90. After I do this I put the 4 bar sample at the beginning of the song and it seems to match up for like a couple of beats but drifts off beat wtf? I properly trim down the 4 bar sample,I tried all the time stretch settings still off beat, I also tried it with different samples. Any suggestions? I already searched this forum and seen the time stretch tutorial still a no go.
