Regarding styles from older model keyboards.
Maybe those from the KN1000 are too simple, but I use a lot of my old files from the KN2000 that were tailored for specific songs.
The trick, of course is to use the updated (for Kn7000) styles that were so graciously supplied on the Technics web site.
I use these because of not being able to find native KN7000 styles that were really suitable. Don't get me wrong, the KN7000 styles are very good, but different. Besides, I have a lot of work that I put into my files for the KN2000 that I was able to salvage this way.
The best of two worlds.
