Bite the bullet.
Quantizing multi-tracked drums:
It’s important that all the edits and cuts happen at the exact same place on each of the multi-tracked drum tracks to maintain phase coherency.
Make sure they all have the same transient markers. It’s better to chop them up and move the slices around.
Disable the transient markers on the overheads (right click select all -> right click over a marker and disable). Work with the close mic sounds as the source for establishing transients.
Select all the drum tracks. Right click on any track, choose merge and lock markers. Little yellow locks will show up on the clips. All the transient markers from all the drum tracks are copied to each drum track. All the drums share identical transient markers.
The next step is to unlock the clips. Switch back to clip view on all the drum tracks (control + shift + click and select clip). Right click in the background select clip lock and uncheck lock position.
Switch back to audio transient view. The yellow locks should be off.
Call up the Audiosnap palette and select split beats to clips. Now that the clips are split you can use the quantize process. Process -> Quantize -> select a note value (1/8
th) under resolution and audio clip start times under change. Leave auto Xfade times and fill gap checked ( 20ms and 80ms). Click OK.
