i have one and use it with cubase vst 5.1 - it works quite well, but it´s possibilities are a bit limited. the buttons to the left and right of the faders aren´t functional in vst initially - you have to run a little helper program in the background to get them working. for further vst control capabilites look at the list from steinberg below.
in fact it´s primarily designed for pro tools and there it really shines - at least that´s what i heard! i think i also heard somewhere that sonar and samplitude both support
the motormix but i cannot comment on the degree of integration, sorry! maybe there´s also a list like the following from the other manufacturers?
cheers!
