MIDI Implementation

Program Change

Status

2nd byte

CnH

ppH

n = MIDI channel number:

0H - FH (ch.1 - 16)

pp = Program number:

00H - 7FH (prog.1 - prog.128)

*

These messages are transmitted when Patch is selected. But not transmitted when
Transmit Program Change parameter (SYSTEM Com MIDI/USB) is OFF.

Channel Pressure

Status

2nd byte

DnH

vvH

n = MIDI channel number:

0H - FH (ch.1 - 16)

vv = Channel Pressure:

00H - 7FH (0 - 127)

Pitch Bend Change

Status

2nd byte

3rd byte

EnH

llH

mmH

n = MIDI channel number:

0H - FH (ch.1 - 16)

mm, ll = Pitch Bend value:

00 00H - 40 00H - 7F 7FH (-8192 - 0 - +8191)

System Realtime Messages

Active Sensing

Status
FEH

*

This message is transmitted at intervals of approximately 250 msec.

*

This message is not sent when Transmit Active Sensing parameter (SYSTEM Ctrl Tx) is
OFF.

System Exclusive Messages

Universal Non-realtime System Exclusive Message and Data Set 1 (DT1) are the only
System Exclusive messages transmitted by the V-Synth.

Universal Non-realtime System Exclusive Message

Identity Reply Message

Address:

lower middle byte of the starting address of the data
to be sent

ddH

The amount of data that can be transmitted at one time depends on the type of data, and
data will be transmitted from the specified starting address and size. Refer to the address
and size given in

“Parameter Address Map”

(p. 159).

*

Data larger than 256 bytes will be divided into packets of 256 bytes or less, and each
packet will be sent at an interval of about 20 ms.
