Apple Logic Pro 9 - Manual (Page 1047)

You can use the Chord and Transposition tracks to edit the playback transposition of MIDI
events and Apple Loops over time.
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 playhead reaches the next transposition event during
playback.
Transposition events are closely linked to the chord root notes in the Chord track. If you
create or alter a transposition event, the amount of pitch shift is immediately reflected
by the the chord root notes in the Chord track—and vice versa.
The zero position of the Chord and Transposition tracks is determined by the current key
signature in the Signature track. If the key signature changes during a project, the zero
position of the Chord and Transposition tracks changes accordingly.
