Percussion notation is an extension of conventional music notation that allows for non-pitched sounds to be written on either on a single line or on a 5-line drum-staff.
Note however, that notation conventions aren't well established for percussion notation, especially with regard to more unusual instruments.
The default allocation of the general MIDI-drumsound conform the instrument definition file is as follows:
You can change note-head-shape using the table below. Re-applying the same command will turn the note-head to its default shape.
Any part that is meant as a percussion part should use MIDI-channel 10.
Every note/shape combination is mapped onto the available MIDI-notes by means of the section [DRUMMAP] in the instrument definition file
