Alright... I've made a few blends, but i don't have any technique really. I just create a loop that i'm satisfied with, and I stretch it to match the bars I want. Sometimes the voices end up being off beat... or if its the whole song.. little by little the whole things goes off beat. Whats the secret?

Get it as close as possible. Change your BPM clock in smaller increments.... For instance, on 96 BPM. Try 96.25 if that is too slow try 96.50, then 96.75 and so on. When you've got it as close as possible. You can split your accapella right where your audio starts to drift. (preferable where the wave is small or quieter) Shift the wave on to right to the left or right. Make sure your wave is not locked to grid or you won't be able to place wave correctly.
