I am able to use my Analog Experience The Laboratory 49 as a master controller for all of my soft synths within Roland/Cakewalk's Sonar Producer Edition 8, including the Arturia, Dimension Pro, Kontact FM7, PSYNII, Emu's E3 Software sampler (which has plenty of usable piano's), Roland's Real Piano or whatever it's called, and several more. Some of them configure a bit differently as far as various controllers (Filter/Resonance, etc...) are concerned since they're not relative to the Laboratory global controllers, but the basics like sustain, volume, mod, pitch & all those is normal. From there, you'd have to assign them as desired in each soft synth.
