It's a java app.
I got sound in tuxguitar (also a java app) connected to 'midi through port-0 [14:0] ' of my maudio audiophile soundcard... but I can't connect Impro-Visor to that port-... it doesn't show up in the app.
please (at least) note it in your thread and mails when you're crossposting something. If a question is discussed an LAD or LAU, it is not very productive to start a parallel thread here and fork the discussion. People can't easily see what was discussed on the list and vice versa.
I worked this out recently for Impro-Visor (I have a Delta 1010LT, which
also does not have MIDI). It has to do with connecting raw MIDI with a
sequencer like timidity:
Step 1:
sudo modprobe snd-virmidi
Step 2:
timidity -iAqqq -B8,8 & # don't know if the -B8,8 is really necessary
Step 3:
connect the first VirMIDI port to the first Timidity port (I use
qjackctl and the ports are under the ALSA tab in the Connections window)
Step 4:
In Impro-Visor, select the first VirMIDI port for output (or whichever
one you connected to Timidity in Step 3).
Play and enjoy!
Google "timidity virmidi" to find several pages describing various
aspects of this, including how to use aconnect to accomplish Step 3.
