MIDI System Exclusive Packet Head
Several data bytes define the "SysEx Packet Head." Among these are
the standard "Start of Exclusive" also known as SOX, a standard MIDI
Manufacturer's ID assigned by the MIDI Manufacturers Association (MMA)
and Aviom proprietary product and message type identification. SysEx
messages that contain incorrect or unknown ID information or unsupported
message types are ignored by the A-16R without generating error indications.
The MIDI SysEx packet head of an A-16R SysEx packet is described below.

MIDI System Exclusive Packet Tail
Every complete MIDI System Exclusive message should contain a Trailer/Tail
byte referred to as an "End of Exclusive" or EOX for short. Reception of
implemented System Exclusive messages in the A-16R that do not contain an
EOX will be treated as incomplete and flagged as an error.
