no can't figure out the changes. probably fixed a few things but nothing new or let me qualify that statement. i didn't find anything new haha. you can check out platinum samples jo baresi evil drums sdx at www.sweetwater.com or you can find it on the toontrack website www.toontrack.com also check for demo videos on utube. i especially like the kit it loads up with. in myopinion the sdx for superior drummer with the best punchy sound. it's a large expansion. i think about 30 odd gigs. i think i read somewhere that it's on special now. well that was a week or so ago so the special might be over. hth if you can find the info you want contact me off list. kind regards
