1. Receive data
■Channel Voice Messages
●Note off
Status 2nd byte
8nH kkH
9nH kkH
n = MIDI channel number: 0H - FH (ch.1 - 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 byte
9nH kkH
n = MIDI channel number: 0H - FH (ch.1 - 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, these messages are not received when Rx.NOTE ON = OFF for each
Instrument.
●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 byte
BnH 00H
BnH 20H
n = MIDI channel number: 0H - FH (ch.1 - 16)
mm, ll = Bank number: 00 00H - 7F 7FH (bank.1 - bank.16384), Initial value = 00 00H
* Not received when System: Prog TxRx = OFF. (Initial value is ON)
* Not received when Rx.BANK SELECT = OFF.
* Rx.BANK SELECT is set to OFF by GM1 System On, and Bank Select messages 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).

vv = Modulation depth: 00H - 7FH (0 - 127)
* Not received when System: Mod TxRx = OFF. (Initial value is ON)
* 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 byte
BnH 05H
n = MIDI channel number: 0H - FH (ch.1 - 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 byte
BnH 06H
BnH 26H
n = MIDI channel number: 0H - FH (ch.1 - 16)
mm, ll = the value of the parameter specified by RPN/NRPN
mm = MSB, ll = LSB
❍Volume (Controller number 7)
Status 2nd byte
BnH 07H
n = MIDI channel number: 0H - FH (ch.1 - 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)
❍Panpot (Controller number 10)
Status 2nd byte
BnH 0AH
n = MIDI channel number: 0H - FH (ch.1 - 16)
vv = Panpot: 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)
❍Expression (Controller number 11)
Status 2nd byte
BnH 0BH
n = MIDI channel number: 0H - FH (ch.1 - 16)
vv = Expression: 00H - 7FH (0 - 127), Initial value = 7FH (127)
* 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 byte
BnH 40H
n = MIDI channel number: 0H - FH (ch.1 - 16)
vv = Control value: 00H - 7FH (0 - 127)
* Not received when Rx.HOLD1 = OFF. (Initial value is ON)
❍Portamento (Controller number 65)
Status 2nd byte
BnH 41H
n = MIDI channel number: 0H - FH (ch.1 - 16)
vv = Control value: 00H - 7FH (0 - 127) 0 - 63 = OFF, 64 - 127 = ON
* Not received when Rx.PORTAMENTO = OFF. (Initial value is ON)
