3 Enter the inverted Transposition values of the chord root note changes in the Region
Parameter box of each section, so that playback of the Apple Loop parts will match the
original Apple Loop file.
As an Example:
• The Apple Audio Loop contains a chord progression with root notes of: C, F, G, and
C. Cut it at the position of these chord changes.
• Enter C, F, G, and C at the corresponding positions in the Chord track. Assuming the
original key is C, this is equivalent to a transposition of the second Region to +5 and
the third Region to +7. If you played the whole part in this state, the original
transposition of the audio material would be transposed by the amounts just entered
in the Chord track, which isn’t what you want!
• Set the Transpose value of the second Region to −5, and of the third Region to −7 in
their respective Region Parameter boxes.
Playback of the whole part will now sounds just like it did before, and the correct
chords are displayed in the Chord track.
Handling Chord Symbols
The chord symbols in the Chord track can be selected, moved, copied, and deleted via
the usual methods, as described for most of the other Global tracks.
Editing Chord Symbols
If you want to edit a chord, just double-click on it. A dialog box will open, allowing free
changes to the chord symbol properties.
Transposition Track
The Transposition track shows global transposition events, which affect the
transposition of both Audio and MIDI Regions. In MIDI regions, it changes the actual
MIDI events themselves. Despite this data change to events, the Transposition track
works “non-destructively”, as the global transposition of MIDI Regions can be changed
multiple times, without actually altering any information. If the Transposition track is
set to zero, Regions (and the events they contain) are played back as originally
recorded.
