Assigning of TR-808’s sound generators to individual MIDI notes (instrument map) is user
programmable with help of MIDI SysEx messages. Assigning programmed during factory setting is
listed in table 2 (also see pic. 4). That setting conforms to C/M, GM, GS, XG standards. Complete
drum maps of these standards are listed in table 5 (see appendix C.).

TR808-M interface receives info about dynamics too – “Velocity“ value of Note-On MIDI
commands is converted to output level of acoustic signal outgoing from assigned sound generators.
Independent conversion slope (i.e. dynamic range of assigned sound generator) can be defined for
each of acceptable MIDI notes. Conversion slope can be defined with help of MIDI System Exclusive
Messages. Dynamic range programmed during factory setting is listed in table 2.
Required dynamic range of assigned sound generator is specified with values of “Dynamics
From“ and “Dynamics To“ parameters (see pic. 5). “Dynamics From“ defines output level sound
generator if value of “Velocity“ is 1 and “Dynamics To“ defines output level of sound generator if value
of “Velocity“ is 127.
