If you like csound or cycling 74 stuff or reaktor or are interested in mpeg4 standard this is worth a look. Seems to have a creative supportive community so I'll put that for customer support although it's way more valuable. I don't really know what to say about the sound because you can theoreticaly write your own modules and then hook them up any which way you like. If only it had a robust sequencer it would be my weapon of choice.
Take a look.
