Re: [pygame] pygame.midi not working on Ubuntu Jaunty?

[Lenard Lindstrom <len-l@xxxxxxxxx>]

That is unusual. I am using Debian lenny. Pygame 1.9.1 uses portmidi. 
The Pygame midi.py output example works for me whether Timidity is 
started at boot time or from the console - "timidity -iA &". The 
vir_midi module is not needed.
