7. SYSTEM EXCLUSIVE MESSAGES (XG Standard)
(1) XG Native Parameter Change
Data format: [F0H] -> [43H] -> [1nH] -> [4CH] -> [hhH] ->
| [mmH] |
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 | |
llH = | 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]
| [bbH] |
| [ccH] |
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 | |
llH = | Address Low |
ddH = | Data |
ccH = | Check sum |
F7H = | End of Exclusive |
•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
•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 (YDP common) |
or |
|
7F= | Extended Product ID |
xxH = | Product ID |
nnH = | Substatus |
nn | Control |
02H | Internal MIDI clock |
03H | External MIDI clock |
06H Bulk Data (the bulk data follows 06H) | |
F7H = | End of Exclusive |
*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] |
F0H = | Exclusive status |
43H = | Yamaha ID |
73H = | Digital Piano ID |
7FH = | Extended Product ID |
xxH = | Product ID |
11H = | Special control |
0nH = | Control MIDI change (n=channel number) |
cc = | Control number |
vv = | Value |
F7H = | End of Exclusive |
Control | Channel | ccH | vvH |
|
Split Point | Always 00H | 14H | 14H : Split Key Number | |
Metronome | Always 00H | 1BH | 00H : off | |

| 7FH : No accent | |
Damper Level | ch: | 3DH(Sets the Damper Level | ||
|
|
| for each channel) | |
|
|
| ||
Channel Detune ch: | 43H (Sets the Detune value | |||
|
|
| for each channel) | |
|
|
| ||
Voice Reserve | ch: | 45H | 00H | : Reserve off |
|
|
| 7FH : on* | |
*When Volume, Expression is received for Reserve On, they will be effective from the next Key On. Reserve Off is normal.
10.SYSTEM EXCLUSIVE MESSAGES (Others)
Data format: [F0H] -> [43H] -> [1nH] -> [27H] -> [30H] -> [00H]
-> [00H] -> [mmH] -> [llH] -> [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. |
27H = | Model ID of TG100 |
30H = | Sub ID |
00H | = |
00H | = |
mmH = Master Tune MSB | |
llH = | Master Tune LSB |
ccH = | don’t care (under 7FH) |
F7H = | End of Exclusive |
