Hi,
I'm not sure I will ever need it, but getting MIDI stuff out of
Musescore seems nice, and I was trying to get it connected to a
Virtual MIDI keyboard (as in
http://www.youtube.com/watch?v=f_jlej7cnQA), but I cannot get it to work.
I have Ubuntu Studio 10.04, VMPK version 0.3.0, and Musescore 0.9.6.2
(revision 3400). What I did:
* In Musescore I go to preferences-I/O and select Use JACK MIDI
output. Quit MuseScore (screenshot at:

* Start JACK
* Start VMPK
* Start MUSESCORE
In the Jack Audio Connection Kit Connections view, I see Mscore1
in the MIDI tab as readable client, but VMPK Input only shows in the
ALSA tab, so I cannot connect them. (screenshot at:

Does somebody know if I'm doing something wrong (or forgetting to do
some extra step)?.
You need a bridge between alsa midi and jack midi. a2jmidid will do the
trick. The connect jack midi out from mscore to a2j:vmpk:in
Tip: To get a2jmidid up and running every time you start jack (it
doesn't hurt when you don't need it), in qjackctl, execute after server
start: a2jmidid (add -e option to a2jmidid if you have a real midi
keyboard).
By the way, in case I try to connect them directly with Patchage, I
get the message Cannot connect Jack audio port to Alsa Midi port!,
so is it considering the mscore-midi-1 as a Jack audio port???

This seems like a bug in your patchage version, which is very old. I
strongly recommend you update it. This is a PPA with a much more recent
version of patchage for lucid:
