I don't know a lot about the KN, so I'll leave the sound things to those who know better, ( PA80 will shine for synth stuff though ), but from what I do know of the KN, sequencing is supposed to be very good in comparison to other keyboards. The PA80 is also very good in this area. Seemingly complicated at first but with good reason I think. Lot's of detail and capabilities to make good styles. I was able to convert some of the Yamaha styles I had and I think that some of them sound as good if not better on the PA80 than they did on their original boards. I did use external software to assist, but all of the voice editing and tweaking was done in the PA80 with good results.
