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.

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.
