MIDI Master Volume
• Simultaneously changes the volume of all channels.
• When a MIDI master volume message is received, the volume
only has affect on the MIDI receive channel, not the panel master
volume.

When the General MIDI mode ON message is received, the MIDI
system will be reset to its default settings.
This message requires approximately 50ms to execute, so sufficient
time should be allowed before the next message is sent.

Data size must match parameter size.
When the XG System On message is received, the MIDI system will
be reset to its default settings.
The message requires approximately 50ms to execute, so sufficient
time should be allowed before the next message is sent.

• Receipt of the XG SYSTEM ON message causes reinitialization of
relevant parameters and Control Change values. Allow sufficient
time for processing to execute (about 50 msec) before sending the
Clavinova another message.
• XG Native Parameter Change message may contain two or four
bytes of parameter data (depending on the parameter size).
• For information about the Address and Byte Count values, refer to
Table 1 below. Note that the table’s Total Size value gives the size of
a bulk block. Only the top address of the block (00H, 00H, 00H) is
valid as a bulk data address.
8. SYSTEM EXCLUSIVE MESSAGES (Special Control)
