Actually, it is. The System-Exclusive Universal ID command
space is general-purpose functionality that, in many cases,
assumes units talking to each other via cable pairs. See:
http://crystal.apana.org.au/~ghansper/midi_introduction/midi_sysex_universal.html
for details. The simplest example is the Generic Handshaking
instructions, which do flow-control for big Sample Dumps via
a set of commands implementing ACK, NAK, WAIT, EOF, etc.
