* Received during creation of sync tracks in the Sync Track screen.
● Start
Status
FAH
* Received when creation of the sync track begins in the Sync Track screen.
● Stop
Status
FCH
* Received when creation of the sync track is finished in the Sync Track screen.
● Active Sensing
Status
FEH
* When Active Sensing is received, the unit will begin monitoring the intervals of all
further messages. While monitoring, if the interval between messages exceeds
approximately 400 ms, the same processing will be carried out as when Reset All
Controllers is received, and message interval monitoring will be halted.
■ System Exclusive Message
Status Data byte Status
F0H iiH,ddH,......,eeH F7H
F0H: System Exclusive Message status
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).
dd,...,ee = data: 00H - 7FH (0 - 127)

Byte Explanation
F0H Exclusive status
7EH ID number (Universal Non-realtime Message)
dev Device ID (dev: 10H - 1FH, 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.
