cool, thanks for the input. I've been doing a lot of research even before i posted originally.
I've decided that i wanna sell my Numark Stealth and Audio2 and buy a Gigaport HD to use with my ddm4000.
I'm gonna try out mixing externally, which works out anyway in terms of midi controls bc i can still program parts of the ddm for midi, and im gonna get 2 dj-tech kontrol one's in the near future :D
