1.1 System Section
The System Section consists of a sound generator (sound source), a performance controller part (performance), 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.
