Mark, you might wish to recheck your calculations.  As you say,

A three byte Note On message would contain 3*10 = 30 bits.  At 31,250 bits/sec,
that's only 960 microseconds (0.96 milliseconds) duration.  To put it in
perspective, in 960 micoseconds, sound in air travels only about a foot.  A
chord arpeggiated with successive notes separated by a millisecond will surely
be perceived as a single event.
