7. 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 sys-
tem 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.
(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

H =
Address Low
ddH = Data

• Receipt of the XG SYSTEM ON message causes reinitializa-
tion of relevant parameters and Control Change values. Allow
sufficient time for processing to execute (about 50 msec)
before sending the YDP-123 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
(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)
or
7F=
Extended Product ID
24H = Product ID

When nn=02H or 03H, YDP common ID (01H) is rec-
ognized as well as 75H.
9. SYSTEM EXCLUSIVE MESSAGES (Special Control)
Data format: [F0H] -> [43H] -> [73H] -> [66H] -> [11H] ->
[0nH] -> [ccH] -> [vvH] -> [F7H]
F0H = Exclusive status
43H = Yamaha ID
73H = Digital Piano ID
7FH = Extended Product ID
24H = Product ID
11H = Special control
0nH = Control MIDI change (n=channel number)

10. SYSTEM EXCLUSIVE MESSAGES (Others)
