FAH Recorder start Recorder start
Not received when the MIDI clock
is set to Internal.
FCH Recorder stop Recorder stop
Not received when the MIDI clock

Reset All Controllers as when those
signals are received.
• Caution: If an error occurs during MIDI reception, the Damper, Sostenuto,
and Soft effects for all channels are turned off and an All Note Off occurs.

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 suffi-
cient time should be allowed before the next message is sent.
• Panel data send requests cannot be received.
