Chapter 7 Work with tracks 188
Show or hide the subtracks for a Track Stack
m Click the disclosure triangle to the left of the track icon in the main track.
To show or hide the subtracks for all track stacks in a project, Option-click the disclosure triangle
for any track stack in the project.
Add a track to a Track Stack
m Drag the header of the track you want to add between two of the subtracks in the Track Stack.
Note: When you add a track to a summing stack, its routing changes to the aux assigned to the
main track.
Reorder subtracks
m Drag a subtrack by its header up or down inside the Track Stack.
Remove a subtrack from a Track Stack
m Drag the subtrack outside of the Track Stack (below the last subtrack, or above the main track).
When you remove a subtrack from a summing stack, the track’s output routing changes from the
aux used by the main track to the main outputs.
Flatten a Track Stack
You can flatten a Track Stack, in which case the subtracks again become normal tracks.
•
When you flatten a folder stack, the main track is deleted if its volume fader is set at 0 dB
(unity gain) and it contains no automation data.
•
When you flatten a summing stack, the audio subgrouping is retained, unless there is no audio
processing on the main track aux (no plug-ins, volume fader set at 0 dB, Pan/Balance set to
neutral, and no automation data). In this case, all subtracks (or their audio subgroups) are
routed to the Stereo (or Surround) Main output, and the main track Aux is deleted.
Do one of the following:
m Select either the main track or a subtrack, then choose Track > Flatten Track Stack from the Tracks
area menu bar.
m Control-click the track header of the main track or a subtrack, then choose Flatten Track Stack
from the shortcut menu.
