Locking tracks
If you have write permission for a track and want to prevent other users from making changes to it, you can lock it for your own use only.
To lock a track for your exclusive use, click the “Get exclusive access” button for the track in the Inspector or the track list.
To unlock a track, click the “Get exclusive access” button again so it is no longer lit.
The owner of a project can unlock a track, regardless of who locked it:
When you click the “Get exclusive access” button for a locked track that was not locked by you, a warning message appears.
When you are the owner of the project or track, select “Release Lock” to unlock the track.
Other users can only click “Cancel” to leave the track locked.
