4. PROGRAM CHANGE
Data format: [CnH] -> [ppH]
CnH = Program event (n = channel number)
ppH = Program change number
P.C.#=Program Change number
• 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 program change
number listed above. For example, to specify program change num-
ber 1, you would specify a value of 0.
5. Pitch Bend Change (reception only)
[EnH] -> [ccH] -> [ddH]
ccH = LSB
ddH = MSB
6. SYSTEM REALTIME MESSAGES
[rrH]
F8H: Timing clock
FAH: Start
FCH: Stop
FEH: Active sensing
• If an error occurs during MIDI reception, the Sustain, 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 (reception only)
• 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 vol-
ume.
F0H = Exclusive status
7FH = Universal Realtime
7FH = ID of target device
04H = Sub-ID #1=Device Control Message
01H = Sub-ID #2=Master Volume
ll
H =
Volume LSB
mmH = Volume MSB
F7H = End of Exclusive
or
F0H = Exclusive status
7FH = Universal Realtime
XnH = When received, n=0–F.
X = irrelevant
04H = Sub-ID #1=Device Control Message
01H = Sub-ID #2=Master Volume
ll
H =
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 = irrelevant
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.
