Hello New Yorker.
I think I remember you asking a similar question here a while back
KN6000/6500 And I would agree with the replies that followed in general. I had a kn6000/6500 for about 2-3 years, but was unable to obtain the sounds you are after (Dance sounds at a Pro level that is). The Use of the Controller ball helped a little on "basses" (Moog basses etc), but the controller ball will, I think, be absent in the KN7000 (bad omission IMO).
The Drums, Bass, and Synth sounds were just "OK" IMHO, but would not be acceptable in a professional dance mix (also IMO). Just one Idea though (one I thought of doing) how about getting (say) a Yamaha CS1X or CS2X...(more money I know - but are fairly cheap) to use for your "Dance" sounds, and the KN6000/6500 for the soloist/Piano/Other sounds etc, and the "Meat & Potatoes" sounds as they say. Just a thought. You could then of course use this Synth to play back through the Technics Sequencer (40,000 note capacity)
For me, the KN6500 didn't "cut" for a dance machine, but with the addition of a Drum "N" Bass/Solo Synth, you could do a lot with the Sequencer in conjunction with it. And with a Yamaha CSX1 Weighing only 5.7 KG's its a fairly light affair too.
