Take a look at short Future Music - June 2006 review:
Now here's a little cracker and it's freeware too. It uses white noise to generate sounds, passing it through bandpass filters to create pads, atmospheres, organs and percussive sounds. Novel, cool and a kind of 'sci-fi synth' if you like. It's getting some great feedback and, best of all, it's free as a bird.
ps. Majken updated Chimera plugin - it will no longer crash when running multiple instances on multicore systems.
