D-bus is unimportant for me too. I don't know if JACK1 nowadays provide

at least reduced MIDI jitter on my Linux machine, when I needed it,
that's why I used it to get "high performance".

jack1 has a similar implementation but for the ALSA sequencer API, which means that (1) a2jmidid is no longer necessary (2) it can be used used to communicate with other (ALSA MIDI using) applications, not just hardware.
