760 Chapter 33 Working With 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 pre-defined 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 in the pop-up menu, and double-click on this entry to
name the new drum group.
4 Set the Rel. Pos. (relative position) parameter as desired.
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.
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.
