■Channel Voice Messages
●Note off
Status
2nd byte
8nH
kkH
9nH
kkH
n = MIDI channel number:
kk = note number:
vv = note off velocity:
* For Drum Parts, these messages are received when Rx.NOTE OFF = ON for each Instrument.
●Note on
Status
2nd bytes
9nH
kkH
n = MIDI channel number:
kk = note number:
vv = note on velocity:
* 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:
kk = note number:
vv = key pressure:
* 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.
●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:
mm, ll = Bank number:
* Not received when Rx.BANK SELECT = OFF.
* "Rx.BANK SELECT" is set to OFF by "GM1 System On," and Bank Select message will be ignored.
* "Rx.BANK SELECT" is set to ON by "GM2 System On."
* "Rx.BANK SELECT" is set to ON by power-on Reset or by receiving "GS RESET."
* When Rx.BANK SELECT LSB = OFF, Bank number LSB (llH) will be handled as 00H regardless of
the received value. However, when sending Bank Select messages, you have to send both the
MSB (mmH) and LSB (llH, the value should be 00H) together.
* Bank Select processing will be suspended until a Program Change message is received.
* The GS format "Variation number" is the value of the Bank Select MSB (Controller number 0)
expressed in decimal.
* Some other GS devices do not recognize the Bank Select LSB (Controller number 32).
❍Modulation (Controller number 1)
Status
2nd bytes
BnH
01H
n = MIDI channel number:
vv = Modulation depth:
* 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:
vv = Portamento Time:
* 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:
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:
vv = Volume:
* Volume messages are used to adjust the volume balance of each Part.
* Not received when Rx.VOLUME = OFF. (Initial value is ON)
❍Pan (Controller number 10)
Status
2nd bytes
BnH
0AH
n = MIDI channel number:
vv = pan:
* For Rhythm Parts, this is a relative adjustment of each Instrument's pan setting.
* Some Tones are not capable of being panned all the way to the left or right.
* Not received when Rx.PANPOT = OFF. (Initial value is ON)
❍Expression (Controller number 11)
Status
2nd bytes
BnH
0BH
n = MIDI channel number:
vv = Expression:
* This adjusts the volume of a Part. 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)
❍Hold 1 (Controller number 64)
Status
2nd bytes
BnH
40H
n = MIDI channel number:
vv = Control value:
* Not received when Rx.HOLD1 = OFF. (Initial value is ON)
❍Portamento (Controller number 65)
Status
2nd bytes
BnH
41H
n = MIDI channel number: 0H-FH (ch.1-ch.16)
vv = Control value
: 00H-7FH (0-127) 0-63 = OFF, 64-127 = ON
* Not received when Rx.PORTAMENTO = OFF. (Initial value is ON)
