8. SYSTEM EXCLUSIVE MESSAGES (XG Standard)
(1) XG Native Parameter Change
Data format:
[F0H] -> [43H] -> [1nH] -> [4CH] -> [hhH] -> [mmH] ->
[
ll
H] -> [ddH] -> [F7H]
F0H = Exclusive status
43H = YAMAHA ID
1nH = When received, n=0–F.
When transmitted, n=0.
4CH = Model ID of XG
hhH = Address High
mmH = Address Mid
ll
H =
Address Low
ddH = Data
|
F7H = End of Exclusive
Data size must match parameter size (2 or 4 bytes).
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] -> [bbH] ->
[hhH] -> [mmH] -> [
ll
H] ->[ddH] ->...-> [ccH] -> [F7H]
F0H = Exclusive status
43H = YAMAHA ID
0nH = When received, n=0–F.
When transmitted, n=0.
4CH = Model ID of XG
aaH = ByteCount
bbH = ByteCount
hhH = Address High
mmH = Address Mid
ll
H =
Address Low
ddH = Data

ccH = Check sum
F7H = End of Exclusive
• 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
instrument 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.
9. SYSTEM EXCLUSIVE MESSAGES
(Digital Piano MIDI Format)
Data format:
[F0H] -> [43H] -> [73H] -> [xxH] -> [nnH] -> [F7H]
F0H = Exclusive status
43H = Yamaha ID
73H = Digital Piano ID
01H = Product ID (digital piano common)
nnH = nn=02 (Internal MIDI clock), nn=03 (External MIDI clock)
F7H = End of Exclusive
10. SYSTEM EXCLUSIVE MESSAGES (Others)
Data format:
[F0H] -> [43H] -> [1nH] -> [27H] -> [30H] -> [00H] ->
[00H] -> [mmH] -> [
ll
H] -> [ccH] -> [F7H]
Master Tuning (XG and last message priority) simultaneously
changes the pitch of all channels.
F0H = Exclusive Status
43H = Yamaha ID
1nH = When received, n=0–F.
When transmitted, n=0.
