Kawai K5000 series

There's nothing in the files folder? What's up with that?

According to the archive for Eat At Joe's old K5000 page, there should 
be plenty of files floating around that some of us have heard of but 
have never been able to find.. Such as "WAV2ADD", or the "K5K 
Cuisinart"? Or even the SoundDiver K5000 OEM version.. Anyone have any 
leads on these? Is there another reference site I'm missing? I'm 
surprised at the lack of resources available for the K5000.
