Status 2nd Byte 3rd Byte
BnH 1CH vvH
* This transmits the value when the [CONTROL 1] knob has been operated.
{ Undened (Controller Number 29)
Status 2nd Byte 3rd Byte
BnH 1DH vvH
* This transmits the value when the [CONTROL 2] knob has been operated.
z Program Change
Status 2nd Byte
CnH ppH
pp= Program Number: 00H–7FH (1–128)
* When a video input or memory number has been selected, this transmits a
program number along with a bank select. For information on control for bank
select and program change, refer to “Bank Select” (p. 13).
System Exclusive Message
Status Data Byte Status
F0H iiH,ddH,...,eeH F7H
F0H: Status of system exclusive message
ii= ID number: This is the ID to recognize manufacturer of the exclusive
message (manufacturer ID). The manufacturer ID of Roland
is 41H. The ID numbers of 7EH and 7FH are expansion of MID
standards and used as universal non-realtime message (7EH) of
universal realtime message (7FH).
dd,...,ee= data: 00H–7FH (0–127)
F7H: EOX (end of exclusive)
z Data Set 1 (DT1)
This is the message of actual data transmission. Use this when you want to set data
to the unit.

* Data exceeding 256 bytes should be divided into packets of 256 bytes or smaller. If
you send sequentially, the intervals of packets should be longer than 20 ms.
