bbH, ccH, ddH, eeH, ... ffH, sum
Byte Explanation
F0H Exclusive status
41H ID number (Roland)
dev Device ID (dev: 00H - 1FH, 7FH)
00H Model ID #1 (VC-2)
00H Model ID #2 (VC-2)
0DH Model ID #3 (VC-2)
12H Command ID (DT1)
aaH Address MSB
bbH Address
ccH Address
ddH Address LSB
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. 6).
* 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. 14)
* Not received when the Receive Exclusive (Rx Sys-Ex) parameter (SYSTEM
Common MIDI/USB) is OFF.
