1. Receive data
Channel Voice Messages
Note off
Status
2nd byte
8nH
kkH
9nH
kkH
n = MIDI channel number:
0H-FH (ch.1-ch.16)
kk = note number:
00H-7FH (0-127)
vv = note off velocity:
00H-7FH (0-127)
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each
Instrument.
* The velocity values of Note Off messages are ignored.
Note on
Status
2nd bytes
9nH
kkH
n = MIDI channel number:
0H-FH (ch.1-ch.16)
kk = note number:
00H-7FH (0-127)
vv = note on velocity:
01H-7FH (1-127)
* Not received when Rx.NOTE MESSAGE = OFF. (Initial value is ON)
* For Drum Parts, not received when Rx.NOTE ON = OFF for each Instrument.
Polyphonic Key Pressure
Status
2nd bytes
AnH
kkH
n = MIDI channel number:
0H-FH (ch.1-ch.16)
kk = note number:
00H-7FH (0-127)
vv = key pressure:
00H-7FH (0-127)
* Not received when Rx.POLY PRESSURE (PAf) = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings, there will be no effect.
* Not Received in Keyboard Part.
Control Change
* When Rx.CONTROL CHANGE = OFF, all control change messages except for Channel
Mode messages will be ignored.
* The value specified by a Control Change message will not be reset even by a Program
Change, etc.
Bank Select (Controller number 0, 32)
Status
2nd bytes
BnH
00H
BnH
20H
n = MIDI channel number:
0H-FH (ch.1-ch.16)
mm, ll = Bank number:
00H, 00H-7FH, 7FH (bank.1-bank.16384), Initial Value = 00
00H (bank.1)
* After receiving "GM1 System ON," Bank Select messages will be ignored. After
receiving "GM2 System On" or "GS Reset," Bank Select messages will be recognized.
* Bank Select processing will be suspended until a Program Change message is received.
* Not Received in Keyboard Part.
Modulation (Controller number 1)
Status
2nd bytes
BnH
01H
n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = Modulation depth:
00H-7FH (0-127)
* Not received when Rx.MODULATION = OFF. (Initial value is ON)
* The resulting effect is determined by System Exclusive messages. With the initial
settings, this is Pitch Modulation Depth.

Portamento Time (Controller number 5)
Status
2nd bytes
BnH
05H
n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = Portamento Time:
00H-7FH (0-127), Initial value = 00H (0)
* This adjusts the rate of pitch change when Portamento is ON or when using the
Portamento Control. A value of 0 results in the fastest change.
Data Entry (Controller number 6, 38)
Status
2nd bytes
BnH
06H
BnH
26H
n = MIDI channel number: 0 H-FH (ch.1-ch.16)
mm, ll = the value of the parameter specified by RPN/NRPN
mm = MSB, ll = LSB
Volume (Controller number 7)
Status
2nd bytes
BnH
07H
n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = Volume:
00H-7FH (0-127), Initial Value = 64H (100)
* Volume messages are used to adjust the volume balance of each Part.
* Not received when Rx.VOLUME = OFF. (Initial value is ON)
* Not Received in Keyboard Part.
Pan (Controller number 10)
Status
2nd bytes
BnH
0AH
n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = pan:
00H-40H-7FH (Left-Center-Right), Initial Value = 40H
(Center)
* For Rhythm Parts, this is a relative adjustment of each Instrument's pan setting.
* Not received when Rx.PANPOT = OFF. (Initial value is ON)
* Not Received in Keyboard Part.
Expression (Controller number 11)
Status
2nd bytes
BnH
0BH
n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = Expression:
00H-7FH (0-127), Initial Value = 7FH (127)
* It can be used independently from Volume messages. Expression messages are used for
musical expression within a performance; e.g., expression pedal movements, crescendo
and decrescendo.
* Not received when Rx.EXPRESSION = OFF. (Initial value is ON)
* Not Received in Keyboard Part.
Glide (Controller number 16)
Status

n = MIDI channel number:
0H-FH (ch.1-ch.16)
vv = Control value:
00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* It can be used on only keyboard part. Not received on GS part.
