Long, long ago I made a simple synthesizer for windows using the CoreAudio API (there is a newer one, WASAPI, but I never got it to work well myself since it is so complicated). It's a fun project. It is also easy to add some simple filters this way.
If you don't want to do realtime synthesis, you can also dive in the (uncompressed) WAV file format and make programs that generate sound files.
Another thing that might be nice (but I personally haven't tried) is to synthesize your own drums, 808-style. Google 'kick synthesis' for example.
