•
Track Stacks: Track Stacks let you organize and control multiple tracks, and create
audio subgroups.
•
Folder tracks: Can contain folders, which are containers for other tracks. Folder tracks are not
assigned to a channel strip in the Mixer.
There are additional track types that do not contain regions, including auxiliary (aux) and output
tracks, used for routing the output of other tracks; global tracks, used to control aspects of the
overall project; and the master track, which you can use to control the overall volume level of
the project.

working in the Tracks area, see

tracks, see
Regions
Regions are the building blocks of a project. Each time you make a recording, drag an Apple
Loop to the Tracks area, or add a media file to your project, a region representing the recording
or file appears in the Tracks area.
Regions appear as rounded rectangles in the Tracks area. Different types of regions correspond to
different track types and types of material.
•
Audio regions refer to (point to) an underlying audio file (a recording made in Logic Pro, an
audio Apple Loop, or an imported audio file). An audio region can represent the entire audio
file or only a portion of one. When you edit the region in the Tracks area or the Audio Track
Editor, the original audio file is not changed.
•
MIDI regions contain MIDI data for notes and other MIDI events, such as controller and
program change information. They are stored as part of the project, but can also be saved as
individual files.
In the Tracks area, you can move, copy, and work with both audio and MIDI regions in a variety
of ways to build your arrangement. You can also edit audio regions in the Audio Track Editor,
and edit MIDI regions in the Piano Roll Editor (and the Score Editor). When Show Advanced
Tools is selected in the Advanced preferences pane, you can edit the source audio files for audio
regions in the Audio File Editor.
