this mode.
2. Transmitted Data
■ Channel Voice Messages
● Note off
Status 2nd byte 3rd byte
8nH kkH 40H
n = MIDI channel: 0H - FH (ch.1 - 16)
kk = note number: 18H - 48H (24 - 72)
● Note on
Status 2nd byte 3rd byte
9nH kkH 78H
n = MIDI channel: 0H - FH (ch.1 - 16)
kk = note number: 18H - 48H (24 - 72)
● Control Change
❍ Expression (Controller number 11)
Status 2nd byte 3rd byte
BnH 0BH vvH
n = MIDI channel: 0H - FH (ch.1 - 16)
vv = expression: 00H - 7FH (0 - 127)
* If the EXPRESSION OUT jack on the rear panel is in use, this unit doesn’t send
Expression message via MIDI.
❍ General Purpose Controller 3 (Controller number 18)
Status 2nd byte 3rd byte
BnH 12H vvH
n = MIDI channel: 0H - FH (ch.1 - 16)
vv = control value: 00H, 7FH (0, 127)
* This message will be sent by operating a foot switch locating left side of the expression
pedal.
* If a FOOT SW-L OUT jack on the rear panel is in use, the unit doesn’t send this message
via MIDI.
❍ General Purpose Controller 4 (Controller number 19)

BnH 13H vvH
n = MIDI channel: 0H - FH (ch.1 - 16)
vv = control value: 00H, 7FH (0, 127)
* This message will be sent by operating a foot switch locating right side of the expression
pedal.
* If a FOOT SW-R OUT jack on the rear panel is in use, the unit doesn’t send this message
via MIDI.
❍ Hold 1 (Controller number 64)
Status 2nd byte 3rd byte
BnH 40H vvH
n = MIDI channel: 0H - FH (ch.1 - 16)
vv = control value: 00H, 7FH (0, 127)
* If a HOLD OUT jack on the rear panel is in use, the unit doesn’t send Hold 1 message via
MIDI.
