❍ RPN MSB/LSB (Controller Number 100, 101)
Status 2nd byte 3rd byte
BnH 65H mmH
BnH 64H llH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm = upper byte (MSB) of parameter number speci ed by RPN
ll = lower byte (LSB) of parameter number speci ed by RPN
* Not received when Rx. RPN = OFF. (Initial value is ON)
* The value speci ed by RPN will not be reset even by messages such as Program
Change or Reset All Controller.
**RPN**
The RPN (Registered Parameter Number) messages are expanded control changes,
and each function of an RPN is described by the MIDI Standard.
To use these messages, you must rst use RPN MSB and RPN LSB messages to specify
the parameter to be controlled, and then use Data Entry messages to specify the
value of the speci ed parameter. Once an RPN parameter has been speci ed, all Data
Entry messages received on that channel will modify the value of that parameter. To
prevent accidents, it is recommended that you set RPN Null (RPN Number = 7FH/7FH)
when you have nished setting the value of the desired parameter. Refer to Section 4.
“Examples of actual MIDI messages” <Example 4>
On this instrument, RPN can be used to modify the following parameters.

100/128 Cent/Value
7FH 7FH --- --- RPN null
Set condition where RPN and NRPN are
unspeci ed. The data entry messages
after set RPN null will be ignored.
(No Data entry messages are required
after RPN null).
Settings already made will not change.
mm, ll: ignored
●Program Change
Status 2nd byte
CnH ppH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
pp = Program number: 00H-7FH (prog.1-prog.128)
* Not received when Rx. PROGRAM CHANGE = OFF. (Initial value is ON)
* After a Program Change message is received, the sound will change beginning with
the next Note-on. Voices already sounding when the Program Change message
was received will not be a ected.
●Channel Pressure
Status 2nd byte
DnH vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Channel Pressure : 00H-7FH (0-127)
* Not received when Rx. CH PRESSURE (CAf) = OFF. (Initial value is ON)
* The resulting e ect is determined by System Exclusive messages. With the initial
settings there will be no e ect.
●Pitch Bend Change
Status 2nd byte 3rd byte
EnH llH mmH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
mm, ll = Pitch Bend value: 00 00H - 40 00H - 7F 7FH
(-8192 - 0 - +8191)
* Not received when Rx. PITCH BEND = OFF. (Initial value is ON)
* The resulting e ect is determined by System Exclusive messages. With the initial
settings the e ect is Pitch Bend.
■ Channel Mode Messages
●All Sounds O (Controller number 120)
Status 2nd byte 3rd byte
BnH 78H 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* When this message is received, all currently-sounding notes on the corresponding
channel will be turned o immediately.
●Reset All Controllers (Controller Number 121)
Status 2nd byte 3rd byte
BnH 79H 00H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
* When this message is received, the following controllers will be set to their reset
values.
Controller Reset value
Pitch Bend Change ±0 (Center)
Polyphonic Key Pressure 0 (o )
Channel Pressure 0 (o )
Modulation 0 (o )
Expression 127 (max)
Hold 1 0 (o )
Portamento 0 (o )
Sostenuto 0 (o )
Soft 0 (o )
RPN unset; previously set data will not change
NRPN unset; previously set data will not change
●Local Control (Controller Number 122)
Status 2nd byte 3rd byte
BnH 7AH vvH
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value: 00H, 7FH (0,127)
00H: Local O
7FH: Local On
