You can try using JACK with -Xseq, this will trigger the JACK internal ALSA-JACK MIDI bridge. There's also a direct JACK option for this but that depends on the JACK version you're using. IIRC for Jack2 this is -Xalsarawmidi. You can also use a2jmidid but then you need to start that in the background after having started JACK. Jeremy
