Watching the video I was thinking they should call this thing the Ketron-DNJ. Donny has many times written about using a mix of media (arranger styles, SMF, audio) whatever it takes to please your audience. I have recently taken that advice to heart and have found it to be a very successful approach. I can do all of those things with my T2 but not at the level that this thing was doing it. A keyboard that can do realtime transposition and/or tempo shift. As the Dawg on AI would say. That's the bomb.
