The VS-1680 can transfer and receive the internal parameters information using system
exclusive messages, and also can be controlled by the external devices using system
exclusive messages. The VS-1680 can transmit and receive Universal System Exclusive
messages, Data Request (RQ1) and Data set (DS1) as the System Exclusive message.
❍About Model ID
For Data Request (RQ1) and Data Set (DT1), VS-1680 uses 00H 0EH as a Model ID.
❍About Device ID
System Exclusive messages are not assigned to any particular MIDI channel. Instead, they
have their own special control parameter called device ID. The Roland system exclusive
messages use device IDs to specify multiple VS-1680 units. The VS-1680 sends system
exclusive messages using 00H - 1FH, and receives the system exclusive messages whose
device ID is same as its device ID and 7FH. The value of the device ID is the value set on the
SYSTEM parameter “MID:DeviceID” minus one.

The message is used to request the particular information of the VS-1680. The VS-1680 does
not transmit the message. If the VS-1680 received the message and the device ID of the
message is same as its device ID or 7FH, the VS-1680 transmits the following Identity Reply
message.
