Apple Logic Express 9 - Manual (Page 970)

These options allow you to have two different MIDI notes (different bass drum sounds,
for example) displayed in the same way in the score, or on the same line, but with different
note heads.
5 Create a new mapped staff style by choosing New > Mapped Style in the Staff Style
window, and inserting all staffs, voices, and drum groups as described above, and in
Working with Staff Styles .
• Staff section: Everything is identical to nonmapped staff styles (with the exception of
the missing Transpose and Key parameters, which wouldn’t make sense here).
• Voice section: Below Voice (in the top header line), is a separate Voice column, where
the different voices are numbered automatically. The staff style shown above contains
one staff with five independent voices.
• Horizontal lines: Display the Staffs-Voices-Drum Groups hierarchy, indicating the borders
between these elements. Each drum group belongs to the voice at the same horizontal
position.
• Pos parameter: Affects the vertical positioning of all notes in the corresponding drum
group. The value shown here is an offset that is added to, or subtracted from, the
relative positions (if defined for individual notes in the Mapped Instrument window).
Mapped staff style names are preceded by the # character in the Staff Styles window.
If you are using several MIDI instruments with different drum assignments, you can create
a separate drum map (in the Mapped Instrument window) for each instrument. The list
of drum groups, however, is the same for all instruments in a project. This allows you to
display different drum tracks with the same mapped staff style. All snare drums, for
example, will be displayed in the same way.
To override this behavior
1 Create additional drum groups (Kick2, Snare2, and so on).
2 Create a second mapped staff style to display these drum groups.
