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-840EX sends exclusive mes-
sages 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
ÒDeviceIDÓ minus one.
