SYSTEM EXCLUSIVE*

This message is used to control system exclusives, which are

tone fine adjustments that are unique to a particular machine.

Originally, system exclusives were unique to a particular

model, but now there are also universal system exclusives

that are applicable to machines that are different models and

even produced by different manufacturers.

The following are the system exclusive messages supported

by this keyboard.

■ GM SYSTEM ON ([F0][7E][7F][09][01][F7])

GM SYSTEM ON is used by an external machine to turn on

this keyboard’s GM system. GM stands for General MIDI.

• GM SYSTEM ON takes more time to process than other

messages, so when GM SYSTEM ON is stored in the

sequencer it can take more than 100msec until the next

message.

■ GM SYSTEM OFF ([F0][7E][7F][09][02][F7])

GM SYSTEM OFF is used by an external machine to turn off

this keyboard’s GM system.
