Ableton Live: How to fake groove quantize

Ableton Live (v7 and lower) is lousy when it comes to working with grooves. But there's a workaround that might be useful until Ableton incorporates real groove quantize support in a future version of Live.

The workaround makes it possible to get midi and audio clips to match the groove of a 'master clip'. To get this working you need to set up warp markers on an audio clip and then specify that the clip's warp grid should modify the master tempo of the set. This creates a master tempo automation pattern. The is automation pattern continually nudges your set's tempo forward and back so that the grid lines in the arrange view correspond to the warp points you set up in the master clip.

If that description was a little hard to follow, watch the video below and it will become clear.

Gotchas:

  1. If you need to change tempo during a track this method isn't suitable.
  2. Be careful that you disable warp on single-hit clips that you place on the timeline, unless you want them smeared as the master tempo changes!
  3. Currently, Live only 'notices' the song tempo automation at the beginning of each 16th measure, so you may find in order to transfer a groove at an acceptable 'resolution' it may be necessary to double the song tempo before beginning this process.
  4. If you're using tempo synchronised effects (eg. a delay), these will behave unpredictably if your master tempo is fluctuating rapidly.
