Global Tracks

•

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 song and 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 note of the chords determines 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.

Display Options for Global Tracks

Global tracks are displayed or hidden by repeated use of the View > Global Tracks menu
option. The View > Global Track Components submenu lists the individual Global track
types. You may use these submenu items to toggle the display of each track type, one
by one, or all at once with the Show All/Hide All options. Following the use of any of the
Components commands, the View > Global Tracks command will only toggle the display
of components previously chosen in the submenu.
