1.1 System Section
The System Section consists of a sound generator (sound source), a performance controller part (per-
formance), and functions that are not directly related to Instrument play. In addition to manipulating
Instrument setting parameters, this section is also used to exchange information.
1.2 Sound Generator Section
The Sound Generator Section consists of a common part that does not depend on the channel and a part
that is specific to each channel. Mainly it receives performance information and performs operations.
1.2.1 Sound generator common section
The common section consists of sound generator setting blocks that do not depend on the sound generator
part, such as system effects, mixer master control, etc. These can be controlled by system exclusive
messages that are basically exclusive to this particular Instrument, but several parameters also can be
controlled by general universal system exclusive messages.
