* The amount of data that can be transmitted at once time will depend on the type
of data, and data must be requested using a specific starting address and size.
Refer to the Address and Size listed in "Parameter Dump Request" (page 145).
* If "Data Set 1" is transmitted successively, there must be an interval of at least 40
ms.
* Regarding the checksum please refer to page 146.
Section 2. Transmit data
*When SETUP/MIDI COMMON/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 PART/Part CH.
● 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 COMMON/Tx PC Sw is set to "OFF".
(Initial Value is ON)
* Only the channel assigned to the backing part are sent.
* Bank selects corresponding to each parts instrument are sent when a song is
selected. Also, when instruments are selected for parts, bank selects for the
respective instruments are sent.
❍ Foot control (Controller number 4)
Status 2nd byte 3rd byte
BnH 04H vvH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
vv = Control value: 00H - 7FH (0 - 127)
* This is transmitted only on the channel which is assigned to the drum kit part.
❍ Data Entry (Controller number 6)
Status 2nd byte 3rd byte
BnH 06H mmH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
mm = The value of the parameter specified by RPN.
* Only the channel assigned to the backing part are sent.
*When a song is selected or adjust SONG/PART/Bend Range setting, the pitch
bend sensitivity of the sequencer song data will be transmitted.
Values for the RPN parameter, on the normal mode of TD-6, are as follows.
RPN Data entry
MSB LSB
MSB LSB Explanation
00H 00H mmH --- Pitch Bend Sensitivity
mm: 00H - 18H (0 - 24 semitones)
7FH 7FH --- --- RPN null
set condition where RPN is unspecified.
