I’ve noticed with a few old tracks - perfect example being Rhythim is Rhythim - It Is What It Is - that, presumably because of the equipment used, the track beat grids perfectly in Traktor and then drops and goes out of time.
Is there any way in Traktor two have 2 separate grids to lock the beat to?
A more extreme example would be to have a 4/4 beat track at 130bpm that then switches to, say, 100bpm (which would be odd!)
Like we said the BPM will be off from the point of the second grid marker, but if the song drifts the BPM is going to be off anyway. So if I have a song that drifts I’ll set up an intro loop, usually somewhere pretty close to the first grid marker. Then when I start the next song it’s in sync. Then towards the end I’ll drop another grid marker and have an outro loop close to that. The songs will usually stay in sync long enough to get the job done.
This doesn’t really work for long blends and live bands where the drummer was extremely stoned when they were in the studio. For those instances warping Ableton is your best bet.
Using a second beatgrid marker is key after breakdowns. Sometimes the producer will use a sample that does not hold exactly to the rhythm, so the drop will be a few milliseconds off (or half a beat) BUT the track will continue at the same tempo.
