Global Tracks
All linear editing windows also feature global tracks, which are displayed just below the
Bar ruler, when opened. Click the disclosure triangle to the left of the Bar ruler (labeled
Global Tracks) to view the global tracks.
 Marker track: Contains markers, which are used to identify bar positions and parts of
the project. Their length, text, and color can be edited freely (for details, see
“
 Tempo track: Contains all tempo changes in the project. For further information, see
 Beat Mapping track: Allows you to assign the desired bar position to any musical
event (both MIDI notes and distinct accents in audio regions). This makes it possible
to adjust the musical timeline to the original timing of a MIDI or audio region that
has been recorded rubato (free time, including speeding up and slowing down), or
just without a metronome click. The audible outcome remains unchanged, but the
resulting display will fit the musical timeline.
 Signature track: Contains the basic key of the project, along with all time and key
signatures, as they are displayed in the Score Editor.
 Chord track: Contains chord symbols that can be derived from MIDI regions or
created with the mouse. These chord symbols may also be inserted into the score.
The root notes of the chords determine the transposition (pitch shifting) of all Apple
Loops, and can also affect the playback of MIDI regions.
 Transposition track: Shows global transposition events. It is linked to the progression
of the chord root notes in the Chord track: Changing a chord root will be reflected in
the Transposition track, and vice-versa.
 Video track: Displays frames of a QuickTime movie as thumbnails that are perfectly
synchronized with the music, making it ideal for film scoring. Cuts in the movie can
be automatically detected and marked.
