Show or hide the subtracks for a Track Stack
• In Logic Pro, 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
• In Logic Pro, 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
• In Logic Pro, drag a subtrack by its header up or down inside the Track Stack.
Remove a subtrack from a Track Stack
• In Logic Pro, 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.
In Logic Pro, do one of the following:
• Select either the main track or a subtrack, then choose Track > Flatten Track Stack from
the Tracks area menu bar.
• Control-click the track header of the main track or a subtrack, then choose Flatten
Track Stack from the shortcut menu.
