Lance,
If your sequenced songs or panel memory setups have been saved in Technics format, then they will load directly into the KN7000 and play fairly well. Lets say that you have saved a song on the KN2000 using the beguine rythym. When you play this on the Kn7000 by just loading the file in, most likely the KN7000 will substitute the KN7000 beguine rythym. You may decide that for this particular song you really liked the KN2000 beguine better.
What you do is to download the KN2000 updated beguine rythym from the Technics KN7000 web site and use that instead of the KN7000 beguine. These rythyms from the older keyboards on the Technics site have already been tweaked to work well on the 7000 so that they will sound great.
Of course, you will hear the new sounds of the KN7000 so the result is very good.
I had about 50 setups from my old KN2000 with special intros, endings, ETC. I converted them as above and use them all the time. Didn't lose a thing.
I can't tell you anything about the KN1000 songs.
Perhaps someone who has used KN1000 songs on the 7000 can tell you more about this.
Regards,
Walt
