I would suggest taking some time to check out Curtis Roads¹ work. http://www.asphodel.com/artists/view.php?Id=52&SessionID=573c139b4831aaeac90bc

He has been using and refining grunular synthesis techniques for decades now. To really drill down into this area also, check out his book, ³Microsounds² on MIT press. It is the definitive text on granular synthesis theory and technique. http://mitpress.mit.edu/catalog/item/default.asp?ttype=2&tid=10389
