You are absolutely right. As a matter of fact, adding your own
sreial interrupt handler (Remember my previous posting concerning this?)
and an interrupt handler to the 8520A timer solves all the timing
problems, with the 8520A timer providing the timing needed for the
serial interrupt handler. Currently, no extra hardware except a midi 
interface is needed.
