I'm using Pro X2. I need to increase the speed (but not the pitch) of 13 drum tracks and a couple of guitar tracks. I selected the tracks to change in the Object list (check boxes) and can speed up/shrink the tracks fine in the OE. But once I've selected the tracks, if I click on a different track all of my selected tracks become unselected. Will the tracks hold the time changes (it doesn't sound like they did)? Is it a destructive change? Do I export the selected tracks to new tracks? (Obviously I've not used this feature before). Thanks.
