Frankly i don't remember how I did it, I know it involved lots of lfo cv modulation and a few samplers. I will see if i can submit a more polished version, as I made that one almost by accident XD (sometimes I just sit and experiment, and when I get wicked results that I like I save them)
EDIT: Malcos, the scratching sounds cool. Is that combi an insert, or a scratching sound generator? because mine isn't something that you can insert and converts the sound into scratching, although, I might have an idea of how that could be accomplished... gonna try it when I get home.
