Section 2.
Transmit data
*
When [SETUP]-[MIDI]-[GLOBAL]-[PAGE 3] SOFT THRU is set to “ON”, messages
received in addition to the following messages are also sent.
■
Channel Voice Messages
*
The following channel voice messages are transmitted on the channel specified as the
[SETUP]-[MIDI] TX/RX CHANNEL.
●
Note off
Status
2nd byte
3rd byte
8nH
kkH
vvH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
kk = note number:
00H - 7FH (0 - 127)
vv = Note off velocity:
40H (64) fixed
●
Note on
Status
2nd byte
3rd byte
9nH
kkH
vvH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
kk = note number:
00H - 7FH (0 - 127)
vv = note on velocity:
01H - 7FH (1 - 127)
*
On the channel assigned to the drum kit part, the note numbers specified by the drum
kit will be transmitted.
*
On the channel assigned to the percussion part, the note numbers specified by the
percussion set will be transmitted.
●
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 = value:
00H, 7FH (0, 127)
*
On the channel assigned to the drum part, 7FH will be transmitted when the rim of the
pad is pressed and 00H when the rim is released, for the note number specified for the
head and rim.
●
Control Change
❍
Bank Select (Controller number 0, 32)
Status
2nd byte
3rd byte
BnH
00H
mmH
BnH
20H
llH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
mm = Bank number MSB:
00H - 7FH (bank.1 - bank.128)
ll = Bank number LSB:
processed as 00H
*
Not transmitted when [SETUP]-[MIDI]-[PROG] PROGRAM CHANGE RX SW is set to
“OFF”.(Initial Value is ON)
*
Only the channel assigned to the backing part are sent.
*
Bank selects corresponding to each part’s instrument are sent when songs or patterns are
selected. Also, when instruments are selected for parts, bank selects for the respective
instruments are sent.
❍
Modulation (Controller number 1)
Status
2nd byte
3rd byte
BnH
01H
vvH
n = MIDI channel number:
0H - FH (ch.1 - ch.16)
vv = Modulation depth:
00H - 7FH (0 - 127)
*
This is transmitted only on the channel which is assigned to the drum kit part.
*
If the [SETUP]-[MIDI]-[GLOBAL]-[PAGE 2] PEDAL CC or ZONE CC are set to “MOD”,
the specified parameter will be transmitted.
