Hi JohnC.
Yes I know I for one would be interested in a CD that had a pretty good representative sound of the styles and tone of the KN7000. I would be willing to pay for it.
One kind forum member made a CD for me for the KN2600 and the PSR2100 when I was thinking along those lines.
It seems like its the next best thing to actually playing one, but I would have to agree until one can get their hands on one for a reasonable period of time, then its a lot of guess-work.
I am quite certain from my past experience that I would love to have a KN7000 and probably the new Korg PAX1 61 note version from what I have heard about it. If I had those plus my Tyros I think I would also want a strong roadie.
Best
Scott
