About Device ID
Exclusive messages are not assigned to any particular MIDI channel.
Insted, they have their own special control parameter called device ID.
The Roland exclusive messages use device IDs to specify various
devices.
The VS-840 sends exclusive messages using the device ID 00H - 1FH, and
receives the exclusive messages which device ID is same as its device ID
or 7FH.
The value of the device ID is the value set on the MIDI parameter
"DeviceID" minus one.
