[SOLVED] Natively bridging ALSA MIDI to JACK MIDI

Hi, I want to use a MIDI controller with JACK.  I've read through https://wiki.archlinux.org/index.php/JA … ection_Kit and https://wiki.archlinux.org/index.php/USB_Midi_Keyboards and http://murks.lima-city.de/serendipity/? … mmies.html but still couldn't figure it out really.

I work with jack (not jack2) and have no PulseAudio installed, just ALSA and JACK.  My controller seems to play nice with ALSA, it lists under aconnect and with aseqdump I can see the events produced by it.  However, under JACK no MIDI intup ports are listed (I tried both, the -Xseq and -Xraw option although the second one is not listed in the jackd manual but I found it mentioned in the articles linked above).

I know there is a2jmidid but I just wondered if there might be another possibility, I like to keep things small and simple.  I mean, since JACK provides the -X option it is obviously intended to natively deal with this, right?

Thanks for any help!

Edit: Just so that my solution from below does not appear confusing, in the beginning I tried

jackd -dalsa -Xalsa_midi

, order apparently matters!

This site http://manual.ardour.org/setting-up-you … -on-linux/ mentions the -Xalsa_midi option but it doesn't seem to work either.  I mean, I should be able to see the ALSA MIDI ports with jack_lsp, right?

OK, I had to apply both options, this was the solution!  So

jackd -dalsa -Xalsa_midi -Xseq

did the trick!

OK, just saw that

jackd -Xalsa_midi -dalsa

is working as well...
