❍Data set 1DT1

This is the message that actually performs data transmission, and is used when you wish to transmit the data.

Status	Data byte	Status
F0H	41H, dev, 00H, 43H, 12H, aaH, bbH,	F7H
	ccH, ddH, eeH, ... ffH, sum
Byte	Explanation
F0H	Exclusive status
41H	ID number (Roland)
dev	Device ID (dev: 00H - 1FH, 7FH, Initial value is 10H)
00H	Model ID #1 (RD-700)
43H	Model ID #2 (RD-700)
12H	Command ID (DT1)
aaH	Address MSB: upper byte of the starting address of the data to be sent
bbH	Address: upper middle byte of the starting address of the data to be
	sent
ccH	Address: lower middle byte of the starting address of the data to be
	sent
ddH	Address LSB: lower byte of the starting address of the data to be sent.
eeH	Data: the actual data to be sent. Multiple bytes of data are transmitted
	in order starting from the address.
:	:
ffH	Data
sum	Checksum
F7H	EOX (End Of Exclusive)

*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. 153).

*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.

*Regarding the checksum, please refer to (p. 160)

*Not Received when the GM Mode is ON.

Status	2nd byte	3rd byte
8nH	kkH	40H
n = MIDI channel number:		0H - FH (ch.1 - 16)
kk = note number:		00H - 7FH (0 - 127)

*Note off message is sent out with the velocity of 40H.

●Note on

Status	2nd byte	3rd byte
9nH	kkH	vvH
n = MIDI channel number:		0H - FH (ch.1 - 16)
kk = note number:		00H - 7FH (0 - 127)
vv = note on velocity:		01H - 7FH (1 - 127)

●Control Change

*By selecting a controller number that corresponds to the setting of parameters of controllers (Control Src, Foot Controller Assign), the RD-700 can transmit any control change message.

*These messages are not transmitted when MIDI Tx Parameter is OFF.

❍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 - 16)
mm, ll = Bank number:		00 00H - 7F 7FH (bank.1 - bank.16384)

*When Rec Mode is ON (EDIT:Utility:Rec Setting:Rec Mode), these messages are transmitted when Tone is selected.

*These messages are transmitted when Bank Select parameter is Set on MIDI Tx Part.

*The Bank Select Numbers corresponding to SRX series should be referred to the SRX series owner’s manual.

❍Modulation (Controller number 1)

Status	2nd byte	3rd byte
BnH	01H	vvH
n = MIDI channel number:		0H - FH (ch.1 - 16)
vv = Modulation depth:		00H - 7FH (0 - 127)

*These messages are transmitted when Modulation lever is operated.

❍Portamento Time (Controller number 5)

Status	2nd byte	3rd byte
BnH	05H	vvH
n = MIDI channel number:		0H - FH (ch.1 - 16)
vv = Portamento Time:		00H - 7FH (0 - 127)

*These messages are transmitted when Portament Time is set in MIDI Tx Mode.

❍Data Entry (Controller number 6, 38)

Status	2nd byte	3rd byte
BnH	06H	mmH
BnH	26H	llH

n = MIDI channel number: 0H - FH (ch.1 - 16)
