JACK's option -Xseq will include all hardware MIDI devices (including USB MIDI). I never even had plug-and-play problems.

What's wrong with Aeolus' ALSA midi port? My .aeolusrc doesn't even contain -A and still gives me an ALSA midi port in addition to the JACK midi port.

a2jmidi works fine here, when I have to use it. Very reliably and accurately.llly.
