602 Chapter 25 Mixing
Displaying Folder Tracks
The Mixer can display the channel strips associated with the contents of folder tracks,
or tracks on the highest Arrange window display level.
If a folder track is selected—or the Arrange is showing the contents of a folder when
you open the Mixer—it will only show the channel strips associated with the tracks
within the folder.
If you click the Hierarchy button (to the left of the Mixer Link button), you will switch
the Mixer display up to the next level in the Arrange hierarchy; in this case, the level
containing the folder.
Double-clicking the folder channel will return to displaying the channels within the
folder. The View > Folder Tracks option must be switched on for this to work.
