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.

F0H = Exclusive status
7FH = Universal Realtime
7FH = ID of target device
04H = Sub-ID #1=Device Control Message
01H = Sub-ID #2=Master Volume
llH = Volume LSB
mmH = Volume MSB
F7H = End of Exclusive
or
F0H = Exclusive status
7FH = Universal Realtime
XnH = When received, n=0~F. X = don’t care
04H = Sub-ID #1=Device Control Message
01H = Sub-ID #2=Master Volume
llH = Volume LSB
mmH = Volume MSB
F7H = End of Exclusive

(2) Universal Non-Realtime Message (GM 0n)

General MIDI Mode On

Data format:

[F0H] -> [7EH] -> [XnH] -> [09H] -> [01H] -> [F7H]

F0H = Exclusive status
7EH = Universal Non-Realtime
7FH = ID of target device
09H = Sub-ID #1=General MIDI Message
01H = Sub-ID #2=General MIDI On
F7H = End of Exclusive
or
F0H = Exclusive status
7EH = Universal Non-Realtime
XnH = When received, n=0~F. X = don’t care
09H = Sub-ID #1=General MIDI Message
01H = Sub-ID #2=General MIDI On
F7H = End of Exclusive
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.

7. SYSTEM EXCLUSIVE MESSAGES (XG Standard)

(1) XG Native Parameter Change

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

[mmH] -> [llH] -> [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
llH = Address Low
ddH = Data
|
F7H = End of Exclusive
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.

(2) XG Native Bulk Data (reception only)

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

[bbH] -> [hhH] -> [mmH] -> [llH] ->

[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
llH 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
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)

Data format: [F0H] -> [43H] -> [73H] -> [xxH] -> [11H] ->

[0nH] -> [ccH] -> [vvH] -> [F7H]

F0H = Exclusive status
43H = Yamaha ID
73H = Clavinova ID
67H =
CLP-920 ID
11H = Clavinova special control
0nH = Control MIDI change (n=channel number)
cc = Control number
vv = Value
F7H = End of Exclusive
Control 0n ccH vvH
Voice Reserve ch: 00H-0FH 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.

9. 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 = Transmission from n=CLP is always 0. 0-F is received.
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
