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 suffi-
cient time should be allowed before the next message is sent.

8. SYSTEM EXCLUSIVE MESSAGES (XG Standard)

(1) XG Native Parameter Change

Data format: [F0H] -> [43H] -> [1nH] -> [4CH] -> [hhH] ->

[mmH] -> [ll H] -> [ddH] -> [F7H]

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 suffi-
cient time should be allowed before the next message is sent.

(2) XG Native Bulk Data (reception only)

Data format: [F0H] -> [43H] -> [0nH] -> [4CH] -> [aaH] ->

• Receipt of the XG SYSTEM ON message causes reinitialization

of relevant parameters and Control Change values. Allow suffi-
cient 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.
