Sync-Locked Track Groups - Editing

Editing operations on Sync-Locked Track Groups
The Edit menu commands Cut, Delete and Paste will affect all tracks in the currently selected Sync-Locked Track Group because these commands change the length of the tracks(s).

Examples of editing operations on Sync-Locked Track Groups

 * Cut
 * Silence Audio
 * Trim Audio
 * Paste
 * Label track defined Sync-Locked Track Groups
 * Selecting in label tracks

Cut

 * Before 
 * [[image:SyncLock1a.png|Two sync-locked tracks with audio selected in the top track, ready to be cut.]]


 * After Edit > Remove Audio or Labels > Cut
 * [[image:SyncLock1b.png|The two sync-locked tracks from the previous image, after the cut operation, showing that audio was removed from both tracks, keeping them synchronized.]]


 * Result: Audio has been cut from the lower track as well as the upper track.
 * The same thing happens for Edit > Remove Audio or Labels > Delete because those commands remove audio from a track and the following audio on all sync-locked tracks must move to remain synchronized.

Silence Audio

 * Before 
 * [[image:SyncLock1a.png|Two sync-locked tracks with audio selected in the top track, ready to be silenced.]]


 * '''After Edit > Remove Audio or Labels > Silence Audio
 * [[image:SyncLock03.png|The two sync-locked tracks from the previous image, after the silence operation, showing that audio was silenced in the upper track but nothing happened to the lower track.]]


 * Result: There has been no change in the lower track.
 * This is because "Silence Audio" does not move (change the time position of) any audio in the selected track.

Trim Audio

 * Before 
 * [[image:SyncLock1a.png|Two sync-locked tracks with audio selected in the top track, ready to be trimmed.]]


 * After Edit > Remove Audio or Labels > Trim Audio
 * [[image:SyncLock04.png|The two sync-locked tracks from the previous image, after the trim operation, showing that the leading and trailing audio was trimmed in the upper track but no change was needed to the lower track to keep it synchronized.]]


 * Result: There is no change in the lower track.
 * Although the length of the upper track has changed, it remains synchronized with the lower track.

Paste
Here is the same project but now there is no selection. The cursor is in the top track, and that track is selected as can be seen by darker gray color of the Track Control Panel.


 * Before 
 * [[image:SyncLock05.png|Two sync-locked tracks with no audio selected; the cursor is in the top track which is selected and ready to have audio pasted in.]]


 * After Edit > Paste
 * [[image:SyncLock06.png|Audio has been pasted into the top track moving the following audio to the right; silence has been inserted in the lower track corresponding to the length and position of the pasted region.]]


 * Result: Audio is pasted into the top track moving the following audio to the right.
 * Silence is inserted in the lower track to keep it synchronized with the top track.



Label track defined Sync-Locked Track Groups
Here is a project with two mono audio tracks above a label track all of which are above a stereo music track. There is a selection in the upper mono audio track. The sync-locked selection extends into the second mono audio track and into the label track but not into the stereo music track. The label track defines a Sync-Locked Track Group comprised of itself and the two mono audio tracks above it; this can be verified by examining the Track Control Panels and observing the sync-lock icons at the lower right-hand corners.


 * Before 
 * [[image:SyncLock07.png|Two mono tracks (one containing a selection to be cut) above a label track that separates a stereo track below into a second Sync-Locked Track Group.]]


 * After Edit > Remove Audio or Labels > Cut
 * [[image:SyncLock08.png| The tracks above the label track remain synchronized after the cut, while the stereo track in the second Sync-Locked Track Group is not affected.]]


 * Result: Audio is removed from the two mono audio tracks and labels in the label track are moved so that the three tracks remain synchronized.
 * No audio is removed from the stereo music track.



Selecting in label tracks

 * Selections can be made in a label track and the Sync-Locked selection will extend into any audio and label tracks in the group.


 * Before 
 * [[image:SyncLock17.png]]


 * After Edit > Remove Audio or Labels > Cut
 * [[image:SyncLock18.png]]


 * Result: The selected portion of the label track is removed, including the label spanned by the selection.
 * Audio is removed from the Sync-Locked audio track as well.
