Just my two cents on the library discussions. As an intermediate C 
coder, I am very impressed with how clean and straightforward the 
portmidi api is. I got it working in a day with nothing but the header 
file and example code for docs, so I imagine to real programmers it 
would be cake. I'm also very impressed with the efforts to keep 
portaudio and portmidi parrallelized ( real word? ). Obviously I don't 
have the experience to evaluate it for performance or good design, but 
as far as attracting other coders is concerned, this is a nice library. 
Obviously usability is more important, but if that can be achieved I 
think the future of the portmusic APIs is bright.

N.B: this was on linux only. Will try on windows next with mingw to see 
if that's as easy too.
