No MIDI playback

[Grzegorz Galezowski]

Hi, Joe,
you can try this:
http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_install_MIDI_sound_server_.28Timidity.2B.2B.29
if you want to use midi through timidity.
If you take all the steps described in the article, you should have 
timidity visible in Jack Control in midi tab. Then you just connect 
desired application to it.
It's not available by default, because, as I was told on Ubuntu Studio 
developers list:

"It's non-trivial to detect whether the sound card currently in use has 
working MIDI support, and then configure timidity correctly. Then, there 
is the issue that timidity uses a large amount of CPU time to process 
the sounds. Finally, one might use a USB MIDI device, which may not have 
been detected or installed at install time, so auto-configuration would 
be wasting power on timidity."
