This comes from the german korg website, and shows the potentiall of the instrument...

Only thing that sounds week to me on the Korgs is their brass , violin and reed sections. Where Yamaha has their SA sounds and roland true articulation sounds (Their new organ has them) and many vst's excell at this........
I am affraid these instruments on the Korg just sound a little like ...typicall great keyboardsounds, but nothing naturall and alive..And their grand piano still seems a little metalic..as they allways have..

I could be wrong tough....

All in all the instrument sounds great tough.
