Hi,<br>
I used a2jmidi and it worked great, it's easy to compile... You can
start it automatically in qjackctl settings (start - stop commands)...
It's the only way I know to connect alsa midi to jack midi...<br>
good luck<br>

So, what happens is that my hardware midi ports are only available under the (jack) MIDI tab in qjackctl, but ALSA midi clients are only accessible under the ALSA midi tab. There is a MIDI THRU under the ALSA tab, but I still can't see a way to connect the hardware midi (JACK midi) to ALSA midi clients. What am I missing?
Here's what the ffado site has to say (this was the reason for my original post).
Q: Why doesn't MIDI work?
A: FFADO uses jack-midi, not ALSA midi. Therefore it only works with jack-midi enabled applications. You can use a 'bridge' application named a2jmidi to translate between the two systems. More details can be found here.
