HI BOB,
One thing I have learned about the 9000 is that when you do put a disc in it, it caches everything on it (40 styles on my discs) and then when I punch the button for one of those styles it is there to start playing instantly. You can change the 4 variations while playing and have the three beginnings, breaks, and endings and can change the instrument voices while playing. I can put in one floppy, load it (about a minute) and I can play all night and never load another.
I think this is amazing.
I now have all the KN5000 styles converted to 9000 styles so as you can see I now have what I always dreamed of having. All the features of the 9000 combined with all the styles of the kn5000. I am happy as a clam at high tide.
