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.

Percussion Mapping

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:

Midi Pitch	Instrument	Midi Pitch	Instrument
27	Filter Snap	28	Pink Noise
29	Scratch 1	30	Scratch 2
31	Drum Stick	32	Sine Tick
33	Click	34	Bell Click
35	Acoustic Bass Drum	36	Bass Drum 1
37	Rim Shot	38	Acoustic Snare
39	Hand Clap	40	Electric Snare
41	Low Floor Tom	42	Closed Hi-hat
43	High Floor Tom	44	Pedal Hi-hat
45	Low Tom	46	Open Hi-hat
47	Low-Mid Tom	48	Hi-Mid Tom
49	Crash Cymbal	40	High Tom
51	Ride Cymbal 1	52	Chinese Cymbal
53	Ride Bell	54	Tambourine
55	Splash Cymbal	56	Cowbell
57	Crash Cymbal 2	58	Vibraslap
35	Ride Cymbal 2	60	Hi Bongo
61	Lo Bongo	62	Mute Hi Conga
63	Open Hi Conga	64	Low Conga
65	High Timbale	66	Low Timbale
67	High Agogo	68	Low Agogo
69	Cabasa	70	Maracas
71	Short Whistle	72	Long Whistle
73	Short Guiro	74	Long Guiro
75	Claves	76	Hi Wood Block
77	Low Wood Block	78	Mute Cuica
79	Open Cuica	80	Triangle
81	Triangle 2	82	Shaker
83	Jingle Bells	84	Bell Tree
84	Castanets	86	Hi Timbale
85	Low Timbale

- Midi pitches are numbered such that Middle C is 60, and each semitone is numbered sequentially above and below 60. An octave below middle C is 48 and an octave above middle C is 72.
