MIDI Implementation
1. Receive Data
Messages for the CV and GATE jacks are received if the “MIDI Ch: CV/GATE”
parameter matches the MIDI receive channel parameter. Messages for the AUX
jack are received if the “MIDI Ch: AUX” parameter matches the MIDI receive
channel number. Messages for the BEND jack are received if the “MIDI Ch: Bend”
parameter matches the MIDI receive channel number.
If the “MIDI Ch: *” parameter is set to “OMNI,” all MIDI channel numbers are
received regardless of the MIDI receive channel number.
9 Channel Voice Messages
7 Note O
Status 2nd byte 3rd byte
8nH kkH vvH
9nH kkH 00H
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = Note number: *1 L (Low): 48–96, M (Mid): 24–84, H
(High): 0–60
kk = Note number: *2 24H, 25H, 26H, 27H, 2AH, 2BH, 2EH,
2FH, 31H, 32H, 33H
(36, 37, 38, 39, 42, 43, 46, 47, 49, 50, 51)
vv = Note o velocity: 00H–7FH (0–127)
* Note-o velocity is ignored.
*1 If the “Output Mode: CV/GATE” parameter is set to “CvGt,” this is the note
number received for each “TRANSPOSE” switch (when the “Transpose”
parameter is set to 0).
*2 If the “Output Mode: *” parameter is set to “Trigger,” the note specied by
the “TriggerNote: *” parameter is received.
7 Note On
Status 2nd byte 3rd byte
9nH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = Note number: *1 L (Low): 48–96, M (Mid): 24–84,
H (High): 0–60
kk = Note number: *2 24H, 25H, 26H, 27H, 2AH, 2BH, 2EH,
2FH, 31H, 32H, 33H
(36, 37, 38, 39, 42, 43, 46, 47, 49, 50, 51)
kk = Note number: *3 00H–7FH (0–127)
vv = Note on velocity: *4 01H–7FH (1–127)
*1 If the “Output Mode: CV/GATE” parameter is set to “CvGt,” this is the note
number received for each “Transpose” switch (when the “Transpose”
parameter is set to 0).
The range of notes is output to the CV jack as 0– +5V. If the “TRANSPOSE”
switch is set to L (Low), the output is -1– +4V.
*2 If the “Output Mode: *” parameter is set to “Trigger,” the note specied by
the “TriggerNote: *” parameter is received.
*3 Received if the “LFO Key Trigger: *” parameter is “On.”
*4 Received if the “Output Mode: CV/GATE” parameter is set to “CvGt” and if
the “Output Mode: AUX” parameter or the “LFO Control: *” parameter is set
to “Velocity.”
7 Polyphonic Key Pressure
Status 2nd byte 3rd byte
AnH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = Note number: 00H–7FH (0–127)
vv = Polyphonic key pressure: 00H–7FH (0–127)
* The note number is ignored.
* Received if the “Output Mode: AUX” or the “LFO Control: *” parameter is set to
“After Touch.”
7 Control Change
6 Portamento Time (Controller Number 5)
Status 2nd byte 3rd byte
BnH 05H vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
vv = Portamento time: 00H–7FH (0–127)
* Received if the “Output Mode: CV/GATE” parameter is set to “CvGt.”
* The same eect as the “Portamento Time for CV” is applied.
* Even if portamento time is received, the “Portamento Time for CV” parameter
does not change.
6 Hold 1 (Controller Number 64)
Status 2nd byte 3rd byte
BnH 40H vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
vv = Control value: 00H–7FH (0–127)
0–63 = OFF, 64–127 = ON
* Received if the “Output Mode: CV/GATE” parameter is set to “CvGt.”
6 Portamento (Controller Number 65)
Status 2nd byte 3rd byte
BnH 41H vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
vv = Control value : 00H–7FH (0–127)
0–63 = OFF, 64–127 = ON
* Received if the “Output Mode: CV/GATE” parameter is set to “CvGt.”
* Switches portamento on/o for the CV jack. It is not possible to specify legato.
* Even if portamento is received, the “Portamento SW for CV” parameter does
not change.
6 Control Change Number #1–#31, #64–#95
Status 2nd byte 3rd byte
BnH ccH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
cc = Controller number: 01H–1FH (1–31)
40H–5FH (64–95)
vv = Control value: 00H–7FH (0–127)
* Receives the control change that is assigned by the “Output Mode: AUX” and
the “LFO Control: *” parameter.
