[music-dsp] my own projects

The program is sitting in a zip file at
http://www.nightstudies.net/SoundWorkbench/
If you point the text in SoundWorkBenchIni.txt at the plugin directory for
winamp 2 or winamp 5 then it can play
wave files.

I haven't extricated the source from some other projects, but I'm planning
on making the source available too.

I'm all upset that its throwing an exception on shut down in some place that
the debugger can't debug, but the debug version doesn't have that problem
and BoundsChecker can't find any problem either.
