758 Chapter 33 Working With Notation
 Select all notes, and change their MIDI channel to match that of the upper voice (in
the Event Parameter box).
All notes are displayed in the upper staff, probably accompanied by a lot of ledger
lines.
2 Select the notes that you want to define a beaming connection for, then choose
Attributes > Beaming > Beam Selected (or use the corresponding key command).
3 Select the notes that you want displayed in the bottom staff, and choose Attributes >
Voice/Staff Assignment > Staff below Voice (or the corresponding key command).
This moves all selected notes down to the lower staff, although they still remain part of
the upper voice.
You could also use the reverse approach—first assigning all notes to the lower voice,
then moving some notes to the upper staff with Attributes > Voice/Staff Assignment >
Staff Above Voice.
To display all selected notes in their original staff, use Attributes > Voice/Staff
Assignment > Default Staff.
Rest Display
As always, rests are displayed automatically in Logic Pro, as per the Rest settings in the
staff style. Given the cross-staff beaming situation described above, however, most (or
all) notes belong to the voice of the top staff, and the lower staff will contain rests—
some even at positions occupied by notes. To avoid this potential issue, you should use
a staff style where the automatic rest display is deactivated for the bottom staff’s voice.
Wherever rest display is desired, insert it/them from the Part box, with the mouse.
Drum Notation With Mapped Staff Styles
In MIDI regions that are assigned to drum instruments, each MIDI note usually triggers
a different sound. If such MIDI regions are displayed with a regular staff style, you’ll see
notes with no apparent relationships to the sounds represented by them.
If you want to notate these musically meaningless pitches as a readable drum part—
which uses special percussion note heads—you should use mapped instruments and
mapped staff styles.
