effectively zero latency jitter.
This doesn't work nearly so well when there is more then one sound card,
the MIDI UART has effectively a fixed fifo (USB midi), and there is an
SMM interrupt that cannot be masked.
Well, at least those sound cards that provide both audio and midi
*could* do this - timestamp incoming midi and provide that info
in some way, and requiring similar time stamps for outgoing midi.
