Hello (same in any language isn't it) Pauline...
When you've finally finished transferring all those style files to your new machine have a look at all the extra ones available for you to download and use on Bill Norrie's web site http://mysite.freeserve.com/willumspages/index.html
I had to transfer all these, one style file at a time, from my KN920 via Kn5000 set up and then load them into my new KN7000 before letting Bill pop them onto his web site - enjoy your playing...

Incidentally if you are transferring songs where you have used standard rhythms in the Kn6500 presumably you have to save those settings to composer before you can move them across to your KN7000???
