1. Receive data
Channel Voice Messages
* The following channel voice messages are received on the channel specified as the
[SYSTEM]-(MIDI).
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:
01H - 7FH (1 - 127)
* In the melody parts, the velocity values of Note Off message are ignored.
* When the Trigger Mode of the pad is set to "Shot", the pad part and the percussion parts
will ignore the velocity values of Note Off message.
* When the Trigger Mode of the pad is set to "Gate" or "Trig", the pad part and the
percussion parts will receive only the note numbers which are specified by the patch,
and the same processing will be carried out as when pad is released.
* When recording, this is recorded in the sequencer data itself.
Note On
Status
2nd byte
9nH
kkH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
kk = note number:
00H - 7FH (0 - 127)
vv = note on velocity:
00H - 7FH (0 - 127)
* The pad part and the percussion parts will receive only the note numbers which are
specified by the patch.
* When recording, this is recorded in the sequencer data itself.
Polyphonic Key Pressure
Status
2nd byte
AnH
kkH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
kk = note number:
00H - 7FH (0 - 127)
vv = pressure:
00H - 7FH (0 - 127)
* Only the pad part and the percussion parts can be received.
* The pad part and the percussion parts will receive only the note numbers which are
specified by the patch.
* This is used as the pad pressure data.
* When recording, this is recorded in the sequencer data itself.

00H - 02H (bank1: User Patch bank2, 3: Preset Patch)
ll = Bank number LSB:
processed as 00H
* Only the pad part and the percussion parts can be received.
* Bank select processing will be suspended until a program change message is received.
* Not recorded in the sequencer.

* Only the pad part the and percussion parts can be received.
* This is used as the position data of the pedal connected to the EXP PEDAL/HH CTRL
jack.
* When recording, this is recorded in the sequencer data itself.

n = MIDI channel number:
0H - FH (ch.1 - ch.16)
mm = The value of the parameter specified by RPN.
* Only the melody parts can be received.

* In the melody parts, it is used as the part level of the sequencer pattern data.
* When recording, this is recorded in the sequencer data itself if it is received on the
melody parts.
* In the percussion parts, it is used as the part level of the sequencer pattern data.
* Not recorded in the sequencer if it is received on the percussion parts.
