Several of us here can try to help you with making a midi connection between your KN6K and your PC. But try to be more specific as to what it is you want to wind up with. There's a lot of different end results with midi.
In the meantime, read my cookbook at http://users.erols.com/lcohan/technics/.
Some of it may not apply to your needs, but at least you'll have a better idea of what's involved.
