Only a device ID of 7FH or message matching the BR-1200CD’s device ID is received.

When this message is received, Identity Reply message (стр. 346) 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.
