Disklavier

Thanks to all that posted answers to my question about which model I 
own.  I have often wondered if I could attach my laptop to my piano as 
I always read about here in the postings. I've never even downlaoded 
any files from the group because I wasn't sure how to do it. If I could 
use my laptop or not or did I have to use disks. How to connect the 
laptop to the piano and then would it just play music or would the keys 
actually move also. What software would I need to accomplish this. All 
of these questions were answered so now I'm going to start really 
beginning to enjoy this baby thats basically been sitting in my living 
room for the past 10 or so years, kinda quiet most of the time. Thanks 
again to all, Ray
