-------------------------------------------------------------------
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.
BR-900CD transmits 7FH as the device ID.
