With the audio/midi, I strongly recommend just dropping wav playback for now.  
We can use softsynths like Timidity for wav playback, so this code doesn't 
*need* to be in Jazz at the moment.  I've no problems re-adding wav playback 
later, but in the push to simplify things, I strongly suggest dropping it now 
and working on a solid midi implementation.  The midi stuff that's there is 
already pretty good, but....

The current playback class (I forget what it's called, tPlayer?) is derived 
from wxTimer, so it needs to be completely rewritten.  Pretty much from the 
ground up.  ;)  I would suggest if you want to take a crack at this code, you 
might be better of just trashing the old code and rewriting the playback.  If 
you want a non-system dependency, I recommend PortMIDI, and at this moment I 
wouldn't suggest using anything else other than the Alsa and other driver 
code that's already in Jazz.  The problems with wxTimer for realtime midi 
applications are probably pretty obvious, but I'll be happy to write a 
diatribe for you if you want it.  :)
