I have just read

MIDI, unfortunately is not an open file format, so Ubuntu does not support it by default.

Ubuntu should then inform the user the reason why it cannot play midi format files.

Installing timidity allows playing of midi files but it should play them out of the box or warn the user.

root@asty-desktop:/home/asty# apt-get install timidity

This bug is still valid under Hardy. It occurs when I shutdown the jack server when started on a Native Instruments Audio Kontrol 1 soundcard, or when I close Mixxx set up on the same soundcard.
