Work with Track Stacks
Logic Pro Track Stacks overview
Track Stacks provide a convenient way to organize and control tracks, to manage projects
with high track counts, and to create and manage audio subgroups. You can create a Track
Stack from a group of existing tracks, and use the controls on the master track to control
all the subtracks in the Track Stack.
There are two types of Track Stacks: folder stacks and summing stacks. Both types have
a main track and one or more subtracks. The track header for the main track features a
disclosure triangle that lets you show or hide the subtracks. When you close the stack,
only the main track appears in the Tracks area.
Subtracks can include any track type: audio, software instrument (including layered and
multi-output software instruments), external MIDI instrument, or aux tracks. Folder stacks
can also include summing stacks as subtracks.
Folder stacks
Folder stacks let you combine multiple tracks and control them as one unit, without
changing the audio routing of the individual subtracks. When you create a folder stack, the
channel strip assigned to the main track is called the stack master. Using the main track
or the stack master channel strip, you can mute, solo, and adjust the volume level for the
folder stack. This is similar to the way a VCA master fader functions on a hardware mixing
console.
Individual subtracks in a folder stack can have Smart Controls, but the main track has no
Smart Controls. There are no patches for the main track of a folder stack, and no patch can
be saved when the main track is selected.
There are no regions on the main track of a folder stack, only on its subtracks. When the
folder stack is closed, the main track displays an overview of the combined contents of all
subtracks.
When you mute a folder stack using the Mute button on the main track (or stack master
channel strip), the mute or solo state of individual subtracks is preserved, and becomes
active again when the main track is unmuted.
