Before people get a wrong impression of the Evolver sound, I'd like to add the disclaimer from my site:
Please keep in mind that the above sound examples are not representative for the unit. The Evolver does NOT always sound harsh, distorted and weird and is NOT always detuned 
The sounds only demonstrate my way of programming and playing.
In fact the Evolver has an excellent tuning stability and one can program all kinds off analog stuff as well
