There's more to this than "convention". The SMF Specification says
"the first byte (or bytes) of data is a manufacturers ID (these are
one byte, or if the first byte is 00, three bytes)". Such an ID can
be obtained from the MMA (www.midi.org). I assume the "4th" byte
Doug refers to is either the customary <device_ID> byte, or else
maybe a manufacturer <model id>, but Doug would know best <g>.
