ii = ID number: an ID number (manufacturer ID) to indicate the manufacturer whose
Exclusive message this is. Roland’s manufacturer ID is 41H.
ID numbers 7EH and 7FH are extensions of the MIDI standard;
Universal Non-realtime Messages (7EH) and Universal Realtime
Messages (7FH).

06H Sub ID#1 (General Information)
01H Sub ID#2 (Identity Request)
F7H EOX (End Of Exclusive)
* Only a device ID of 7FH or message matching the BR-1600CD’s device ID is received.
* When this message is received, Identity Reply message (p. 292) will be transmitted.
About Device ID
Exclusive messages are not assigned to any particular MIDI channel. Instead, they have
their own special control parameter called device ID. The Roland exclusive messages use
device IDs to specify various devices.
How to set the device ID:
1. Press [UTILITY], move the cursor to [MIDI], then press [ENTER/YES].
The MIDI settings screen appears.
2. Move the cursor to “Device ID,” then rotate the TIME/VALUE dial to set the device
ID.
The Device ID can be set to any number from 17 to 32. It was set to 17 at the factory.
