Ok, now there’s numerous ways to play MIDIs in Ubuntu 
There’s my previous How To with Audacious. But now Ubuntu should be able to play MIDIs by default through any gstreamer based player with the new gsteamer-plugins-bad package in Hardy. Whoohoo!

Hurray! That should make things a lot easier
I knew a guy named Akshay in Ottawa… That’s pretty cool, I need to play my midis now.
Aw, this thing seems to be using Timidity. Is there no GStreamer plugin to output to the regular MIDI out port? (This because I have connected my MIDI out port to QSynth, which I find a far more accurate and faster softsynth than Timidity…)
You can use timidity as a alsa sequencer (/etc/init.d/timidty start).
But that have problems in sound, sometimes you will hear some tick noise.
