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 MIDI
standards and used as universal non-realtime message (7EH) of
universal realtime message (7FH).

z
Data Request 1 (RQ1)
This is the message to request of “send data” to the connected device. Specify data
type and amount using address and size. When this is received, the unit sends the
requested data as “Data Set 1 (DT1)” message in case the unit is in status where the
sending of data is possible and requested address and size are appropriate. If not, the
unit sends nothing.

* Depending on the data type, the amount of single-time transmission is specified.
It is necessary to execute data request according to the specified first address and
size. Refer to the “3. Parameter Address Map” (p. 28) for address and size.
* See “Example of an Exclusive Message and Calculating a Checksum” (p. 36) for
checksum.

Data Set 1 (DT1)
This is the message of actual data transmission. Use this when you want to set data

* See “Example of an Exclusive Message and Calculating a Checksum” (p. 36) for

* Data exceeding 256 bytes should be divided into packets of 256 bytes or smaller. If
you send data set 1 successively, set interval of 20 ms or longer between packets.
