Remixing Acapellas In Logic 7 Options

[Derok]

Hello,

I am looking for any advise from folks who are using Logic for doing remixes with acapella audio files.
I've noticed that the timing of Logic's metronome doesn't stay consistent with the timing of the audio that I imported into the arrange window. I've gone as far finding the full music versions of certain tunes I want to remix, to help establish the bpm; but the sequencer always gets out of sync with the track after going for a while. Is there something inside Logic that I need to set up in the "preferences" to keep things synced within the program. Any syncing tips would be deeply appreciated.

Thanks,

D.

If you've obtained the vocals from "unofficial" source and it's a known track, check out the BPM from the Internet - there are several DJ BPM databases available. As said above, Logic is rock solid with tempo, if you get out of sync it's because you got the BPM wrong.

If it seems you just can't get it exactly right, you can slice the vocals into smaller bits and then manually nudge the bits into right places. This works fine most of the time if you have the BPM 99% correct, because there will always be small rhytmical inaccuracies in every audio file that's done live by a human and not sequenced by a computer.
