1.4Sound 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.

1.4.1Sound 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.

1.4.2Part 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.
