This is a request for a warp tool to make corrections to the tempo of a full track, to correct ‘drifting’ in order to snap it perfectly into a grid, not allowing any fluctuations or drifts in tempo through the course of the track - every beat locked to the grid.
e.g. suppose that I want to slide in a 4/4 kick under a disco track, which has its original drums played by a drummer. The warp tool employed by Ableton Live serves precisely for this purpose (and likewise Elastic Audio in Pro Tools and Logic Pro).
Or I might just simple want to get any older track by a live band gridded to make for easier DJ mixing. Mixing old disco has always been tricky as most tracks drift (presumably as they were made from tape loops).
This was previously requested 18 months ago but no update since I can see?

This feature would get used LOADs I would suggest.
