Use the global tracks
Global tracks overview
Logic Pro includes a set of global tracks that you can use to control different aspects of the
overall project. You can show global tracks in the Tracks area and in the time-based editors
(including the Audio Track Editor, Piano Roll Editor, and Step Editor). When you show the global
tracks, they appear below the ruler for that particular area.
By default, the following global tracks are available:
•
Arrangement track: Contains arrangement markers, which you can move, copy, and edit to
quickly reorganize a project. For more information, see
Add arrangement markers and Edit
arrangement markers .
•
Movie track: Displays frames of a QuickTime movie as thumbnails that are synchronized with
the ruler, for use in film scoring. Cuts in the movie can be detected automatically and marked.
For more information, see
About the Movie track .
When Show Advanced Tools is selected in the Advanced preferences pane, the following
additional global tracks are available:
•
Marker track: Contains markers, which are used to label bar positions and parts of the project.
Their length, text, and color can be edited freely. For more information, see
Markers overview .
•
Signature track: Contains the basic time and key signatures of the project, along with any
signature changes. For more information, see
Time and key signatures overview .
•
Transposition track: Contains transposition events used to transpose parts of a project up or
down in pitch. Transposition affects MIDI regions and Apple Loops, and can also affect audio
regions. For more information, see
Transposition overview .
•
Tempo track: Contains the project tempo, and all tempo changes in the project. For more
information, see
Tempo track overview .
•
Beat Mapping track: Use to adjust the tempo to follow recordings that do not follow a strict
tempo, without changing the rhythmic feel of the recordings. For more information, see
Beat
mapping overview .
