a while ago I used "-Xalsarawmidi" together with "a2jmidid". I can't say
what I will use in the future. I had no time to use much MIDI with my
latest mobo. However, at least a while ago -Xalsarawmidi didn't replace
a2jmidid, by my scripts both were used.
I just played a little bit and let Ardour do everything instead of using
a script. Seemingly Ardour did not start a2jmidid, but seemingly has
$ cat ~/.jackdrc
/usr/bin/jackd -t 200 -p 2048 -R -T -X alsarawmidi -d alsa -n 2 -r 44100 -p 128 -d hw:HDSPMx579bcc,0 -X alsarawmidi
