Kawai Synthesizers

hi fellow kawai k-4 owners  how's it going , i was wondering how i 
can use my k-4 as a simple midi controller , the basic idea is to 
control vst plugins on my computer through the k-4 , in doing so i 
can download vst plugins of famous korg synths and play on them 
using my kawai k-4  ? what options have to be selected on my kawai 
before i can do that , i already bought a m-audio midi port via the 
usb

thanks

i have been stressed out trying to figure this out for a couple of 
days now
