1.4 Sound Generator Section
The Sound Generator Section consists of a common part that does not depend on the channel and a part that specific to
each channel. Mainly it receives performance information and performs operations.
1.4.1 Sound Generator Common Block
The common section consists of a 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.
1.4.2 Part Block
The parts of the sound generator can be operated and their settings can be changed with Instrument-specific system exclusive
messages and channel messages. This function consists of 32 parts, but channel messages can control only Group B.
The following table shows the fixed relationships between the part numbers and channel numbers of channel messages.
