246 Chapter 8 Global Tracks
Note: All Apple Loops and MIDI Regions will be pitch-shifted accordingly. MIDI Regions
will only be transposed if the No Transpose checkbox is deactivated in their respective
Object Parameter boxes. The “zero position” of the Transposition track is determined by
the current key signature in the Signature track. If the key signature changes during a
song, the “zero position” of the Transposition track changes accordingly. “Regular”
Audio Regions (Audio Regions that are not Apple Loops) will not be affected. Nor will
Apple Loops that do not have a key definition (drum loops, for example).
Handling Events in the Transposition Track
The Transposition track contains nodes that are connected by vertical and horizontal
lines. Each node represents a global transposition event, which determines the global
transposition value until the song position reaches the next transposition event during
playback.
Handling of transposition events works in a similar fashion to Tempo track events: They
are created with the Pencil tool, and can be moved horizontally (along the timeline) or
vertically (changing their transposition value) by dragging them with the mouse. Watch
the help tag during these procedures to see the exact transposition value and bar
position of that particular event.
If you hold Control-Option-Command while clicking in the Transposition track, a text
field will open, allowing direct entry of the desired transposition value. After pressing
Return, a transposition event of the typed value will be created at the clicked position.
To delete a transposition event, select it by clicking on the node itself (or the line to its
right) and press Backspace, or use the Eraser tool.
Transposition events can be copied using the standard Copy and Paste procedure or by
dragging them with the mouse while holding Option.
It is also possible to copy or move multiple transposition events simultaneously, which
can be useful for repeated song sections: Use Shift-click or the rubberband selection
method (while pressing Control) to make the multiple selection, then drag the first
selected event to the desired position (while holding Option for copying), or perform
the Copy and Paste commands. Again, watch the help tag while dragging the events.
