I have the Pure phatt Expansion Card for my Proteus, there's some good sounds on there, Pretty nice sounding Drums and percussion. A lot of played out sounds, but you should tweak to make them your own anyways. If I didn't already have a Keyboard I probably would swoop one, I think it's a pretty good deal. It's basically the same thing as a Mo Phatt but with keys. If you can, you really should go to Guitar Center(Never, ever believe what the employees workin' there tell you, most don't seem to know shit about shit) or some other music store and just peep the sounds, tweak some settings, get a feel for it, and really think, would this provide me with what i'm gonna need for a while? It has expansion slots too, so you can always pick up some more new sounds, those are always a plus
LOL@mr. know it all's about studio shit
