Good to see familiar names on this forum. I have also been folowing the KN6000 forum at Technote. I saw one post that said that the KN6500 would contain a built in hard drive as well as the expansion sound board. That is what I am waiting for. But you can't always bank on forum stuff. Much is just rumor. I will wait for Technics to go to a faster CPU, 128 note polyphony and a hard drive before I upgrade from my KN5000. Cheers!
