If you're a Technics fan then you really need to look at the Korg PA3X - it is the same sort of O/S and pretty intuitive. If I were to move on from my KN7000 that's the only one I'd choose.
No idea what the Rolands do or don't do and how they do it.
I am a technics fan and have owned various models since they came out. I still have the KN7000. I researched and thought the Korg Pa3x was the closest to the Kn. However if you do any sequencing you will be disappointed. The Technics , in my opinion, was years ahead of its time. There are many things that can be done on the KN that cannot be accomplished on the Korg. RC Roger Bellotti
