so here's my addendum to this. as loopop says, mostly more feature requests than buys per se, some of which i would completely agree with (the pushing two buttons to create a mod link is a great one and seems to be based on the hydrasynth ui, as does wanting pat on the buttons, btw).
in terms of the multisample thing, yeah i get that . . . . but here's another review from a guy who says he had done some multisamples for kontact instruments and the iridium plotted those in perfectly (he did NOT use the kontact proprietary fromat from what i can tell).
anyway, most of his review makes me want the thing even more, despite some of his quibbles.
