The discussion has moved on but these statements need to be corrected.
With MIDI, a command to 'turn something on' with up to 128 'intensities'
is 3 bytes worst case and 2 bytes best case.  No where near the 'few
dozen bytes' stated by the previous poster.

MIDI runs at 31.25Khz.  A byte can be sent in 320 microseconds.  That's
about 3 bytes per millisecond or 3000 bytes per second.  That's a few
more than the previous poster's 'several bytes per second' I think.
