Prior to defining the details of a mapped staff style, you should set up all drum groups,
note head shapes, and relative note position parameters in the Mapped Instrument
window.
To create a mapped staff style for drum notation
1 Create a mapped instrument in the Environment, then double-click its icon. For details
about creating mapped instruments, see Mapped Instrument Objects.
The Mapped Instrument window opens. Its default settings correspond to the General
MIDI drum note assignments, but they can be edited.
In the columns to the far right are three parameters relevant to notation.
2 In the Head menu, choose the shape of the note head for notes triggered by this particular
pitch.
A note must be assigned to a drum group to be displayed in a mapped staff style. If it’s
not, it won’t be visible.
3 Choose a drum group in the Group menu.
A number of groups are predefined for the most commonly used drum sounds (Kick,
Snare, Hi-Hat, Toms, Cymbals, and so on).
Note: If you want to define a new drum group for another instrument sound (such as
tambourine), choose New Group from the pop-up menu, and double-click the entry to
name the new drum group.
4 Set the Rel. Pos. (relative position) parameter.
The Rel. Pos. parameter assigns the note to a line in the staff. The note position is relative
to the top line of the staff. Integer values make the note fall on a line; fractional values
result in a note position between two lines.
Note: Positions can also be influenced in the Staff Style window, but this affects all notes
of a particular drum group.
