• 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. For further information, see Editing
Transposition with the Chord and Transposition Tracks.
• 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 is reflected in the
Transposition track, and vice versa. For further information, see Editing Transposition
with the Chord and Transposition Tracks.
• 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
detected automatically and marked. For further information, see Using the Video Track.
