since I updated to ubuntu 10.04 I have this issue: midi through does not appear anymore in the midi connect tab of qjackctl. I already set the midi driver to “seq” in the preferences, and it doesn’t work. Midi-through only appears in the alsa tab.
The only workaround I found is starting a2jmidid, so I get a midi-through connection in the midi tab, which I can route to fst. But this is just more complicated than it used to be… My sound card has never changed, it’s and EDIROL UA-25 usb external sound card that always worked flawlessly since ubuntu 8.04.
Make your connections through Patchage ( http://drobilla.net/blog/software/patchage/ )
It is easy and can see both ALSA and Jack MIDI connection
The connections (audio and MIDI) estabilished through QJackCtl are automatically added inside Patchage, so you can use both.
@vervelover: If you haven’t already tried it you could try my patchbay (JP1 - free to download from my site) all jack-midi ports should show up, I’ve been using it (having started jack with the -x seq option which I think is the same as adding seq in qjackctl). I don’t normally have any need to use alsa-midi after that.
I tried every possible patchbay including yours, but I there is no way I can connect fst to the midi through output without a2jmidid, which is ok but I really dont’ understand why am I forced to this workaround when everything worked flawlessy in Karmic Koala, maybe it’s the updated jack packages pushed into the Lucid release…
