i fully retract my statement. i totally misremembered the quote from
the MTC spec, and didn't redo the math. I think my memory was led
astray by the comment in the spec "Also, in the typical MTC systems we
have imagined it would be rare that normal MIDI and MTC would share
the same MIDI bus at the same time". But you're absolutely right, it
uses less than 10% of the bandwidth and I was totally wrong about
this.
first of all, MTC is not a particularly reliable
protocol unless you
can dedicate the equivalent of a MIDI cable to it. its data rate gets
close to the serial MIDI limit,
Using MTC quarterframe messages uses no more than 240 bytes/second, less
than 1/10th of the bandwidth:
