Drum Set Mapping
If you have are using Apple DLS 3 as your playback device and Drum Set as your playback instrument you will need to know how the drum set instruments are mapped to the pitches on the percussion staff.
By default, the samples of the Drum Kit are mapped to the following pitches:
As well, some extra samples are available at the following pitches:
Since you don't normally want the accidentals to appear you can hide the accidentals so they are not visible. So, for example, if you want to create a pattern of hi-hat open and closed, you would first enter the pitches (G for open and G# for closed):
Then hide all the accidentals using the Hide button in the Accidental Panel - this will not change the playback pitches:
Then use the Articulation Panel to add a "+" above the open hi-hat notes and a "o" above the closed hi-hat notes
Finally, you can change the noteheads to "x" noteheads using the Note Attributes Panel.
The score will now playback with the correct sounds and the score has been modified so that it is notationally correct.
For all the other percussion instruments such as Bass Drum, Snare Drum and Cymbals, the instruments are mapped to the middle three lines of the staff. In some cases (as in the Snare Drum and Cymbal) the space above the middle line plays back a roll. Some experimentation will quickly demonstrate which sounds are mapped to which pitches.
Mixed Percussion Mapping
The Mixed Percussion mapping uses the standard General MIDI mapping for percussion instruments with a few additions and replacements:
