Control timing with the groove track
You can set a track as a groove track, and match (synchronize) the timing of other tracks in
the project to it. When you play the project, the timing of matched tracks adjusts to match the
timing of the groove track.

match the timing of the groove track. When a track is set to match the groove track, time
quantization is unavailable for that track.

To prevent a track from matching the groove track, deselect the Match Groove Track checkbox.
