• When program change reception is turned OFF, no program
change data is transmitted or received.
• When you specify a program change as a number in the
range of 0-127, specify a number that is one less than the pro-
gram change number listed above. For example, to specify
program change number 1, you would specify program
change 0.

7. SYSTEM EXCLUSIVE MESSAGES
(Universal System Exclusive)
(1) Universal Realtime Message
Data format: [F0H] -> [7FH] -> [XnH] -> [04H] -> [01H] ->
[llH] -> [mmH] -> [F7H]
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 n is received n=0~F, whichever is received.
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 On)
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.
