Work with transposition
Logic Pro transposition overview
When Show Advanced Tools is selected in the Advanced preferences pane, you can you
can transpose (change the playback pitch of) MIDI regions and AppleLoops in a project
over time using the Transposition track. The Transposition track contains transposition
points for pitch changes (transposition events). The project transposes at the position of
the transposition point, and remains at the new value until the next transposition point.
Transposition affects both audio and software instrument Apple Loops (except drum loops,
and other Apple Loops with no defined key) as well as MIDI regions. Audio regions other
than audio AppleLoops are not transposed.
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 project, the zero position of the
Transposition track changes accordingly.
Transposition works non-destructively, and transposed MIDI notes return to their original
values when the Transposition value is reset to zero (0). For example, starting with a C3
note event in a MIDI region, adding a transposition point with a value of +2 changes the
note event to a D3. If you change the transposition point to a different value, the note is
transposed by the corresponding amount. When you change the transposition point so
that the transposition value is 0, the note returns to a C3. Similarly, if you copy a region
to different parts of the project with different transposition values, the notes in the region
change by the corresponding amount.
When you add or edit a transposition point, only existing MIDI events in a project are
transposed. MIDI events recorded or created afterward are not affected.
