MIDI Implementation
❍Data set 1 DT1
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, 5FH, 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 (VR-760)
5FH Model ID #2 (VR-760)
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. 109).
* 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. 112.
