What is GM 2?
GM 2 is a recommended standard that allows a higher level of performance
expression and compatibility by extending the number of sounds and by defining
sound editing and effect operations in greater detail than were defined by GM
(General MIDI).
Major differences between GM 2 and the GS format (SC-D70)
Sound generator parameter initialization messages
[GS] GS Reset F0 41 10 42 12 40 00 7F 00 41 F7

Sound selection
[GS] Bank Select MSB and Program Change are used to select sounds.
Bank Select LSB is used to switch the sound map.

If a part other than part 10 is to be used as the drum part, this can be specified using
System Exclusive messages. (p. 31)
< Example > Set part 11 as a drum part (ROOM set):
F0 41 10 42 12 40 1A 15 02 0F F7
MIDI ch.= 11
CC#00 000
CC#32 4
PC# 009
[GM2] Use Bank Select LSB and Program Change.
Bank Select MSB is 121. Use 120 to specify a drum part.
< Example > Set part 11 as a drum part (ROOM set):
MIDI CH= 11
CC#00 120
CC#32 0
PC# 009
The GM 2 sound map differs from the GS format. The SC-D70 normally operates
according to the GS format, but if it receives a GM2 On message it will switch to GM2
mode and use the GM2 sound map. In this case, it will not be possible to select the
SC-D70 sounds.
GM (General MIDI) was
defined in 1991 as
recommended practice
within the MIDI standard
to allow the MIDI
functionality of sound
generators to be
standardized between
manufacturers. It defines
the basic functionality of a
sound generator, such as
the number of parts, the
polyphony, and the sound
map.
