Sustain Pedal Symbols
These two symbols are the only score symbols—apart from notes—that directly
represent MIDI events (MIDI controller #64, sustain pedal on and off ), and thus affect
MIDI playback. Logic Express intelligently inserts the on or off version of the symbol,
depending on the status of the type that preceded it (a sustain off always follows a
sustain on, and vice versa).
Clefs
The clefs in the Part box are generally intended for clef changes in the middle of a part,
for a short section of the music. An example would be cello or bassoon parts, when the
part changes to a higher register. Inserted clefs change the score display, starting at the
precise insert position (which can even be in the middle of a bar).
Note: You shouldn’t use the Part box clefs to change the clef of a whole MIDI region. In
this situation, choose an appropriate staff style (see “
Working With Staff Styles ” on
page 775) for the region.
