Module 1, editing 1, editing multiple tracks:
- In the mixer window in the channel strip group slot, assign a group number to the tracks that you want to group.
- (If you don't have the group slot, control click on a channel strip, select "configure channel strip components", tick "group".
- In the inspector window on the left of your main logic window, select the group, settings, tick "editing" and "quantize-locked (audio)". See screenshot. Now the individual tracks will have a green "Q" button (transient analysis).
- Now you can group edit regions while maintaining phase coherency, even with flex-time.
- P.S. If you shift-click the group slot in the mixer window you can assign MULTIPLE GROUPS to a track. Now you can vary the settings per group, e.g. if you want to enable group volume change on some channels in the group but not the others.
