To change the Voice assignments for the notes in the lower staff, you can either; use
the Voice Separation Tool to draw a line below these notes or, select all notes, and
change their MIDI channel to match that of the upper Voice (in the Event Parameter
box).
Following this, all notes will be displayed in the upper staff, probably accompanied by a
lot of ledger lines. The next step is to define the beaming connections, as desired. This
can be done with the regular note attribute functions (Attributes > Beaming > Beam
selected or the corresponding key command).
Now select the notes that you want displayed in the bottom staff, and choose the
Attributes > Voice/Staff Assignment > staff below Voice menu function (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 choose the opposite 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.
Stem Direction
The default stem direction for notes beamed across staves is towards the center—the
beam is displayed between the two staves, stems in the lower staff point up, stems in
the upper staff point down.
The vertical position and inclination of the beam can be altered by use of the stem
length change functions described above: To move the whole beam in parallel motion,
select all beamed notes, and choose Attributes > Stems > Up or Down to change the
inclination of the beam. Alternately, select the first or last note of the group and apply
the functions.
You can also define the stem direction for all notes with the regular note attribute
functions, thereby placing the beam above the top staff or below the bottom staff. If
you decide that you like the in-between beam better, you’ll need to select all notes,
and choose attributes > Stems > Default.
Rest Display
As always, rests are displayed automatically in Logic, as per the Rest settings in the
Score 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 Score 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.
