IF that is all that's required then sending MIDI clock from a 1000 Hz RTC
should work perfectly. The added jitter of +/- 0.5 ms is less than the time
it takes to transmit a 3-note chord (2.24 ms, with running status) from
a keyboard (assuming someone can play that accurately).

But iff the receiver wants to compensate for the transmission delay, it
will need to have some idea of the 'current speed'.
