The math doesn't seem right here...at 31.25kbaud, 3 bytes (a single note-on)
takes just under 1ms to transmit, so six should take about 6ms...except that
running status is often used so the first note-on is 3 bytes and the next five
are 2 bytes each, so those 13 bytes can be send in just over 4ms, right?

And if we're discussing the <difference> between first and last note-on's
instead of the time to transmit all of them, then we're really considering the
time between the end of the first note-on and the end of the last note-on,
which would be about 5ms without running status and 3.3ms with, yes?

(I'm assuming we're only discussing note-on's here, sent at maximum speed, not
taking into account other controller or real-time messages.)
