Just keep in mind that one of the goals for the professional MIDI users,
will be low MIDI jitter.
We face basically the same problems in the low latency audio case,
and one of the few ways to achieve this will be the use the rtsoundserver
approach.
This poses new questions like what kind of API to use.
MIDIshare or the ALSA sequencer API are the candidates which come in mind.
And with SMPTE timing is even more an issue , so we have to try to get out the
most of the OS and avoid too many communication layers between threads as
much as possible.
