Hi Maurice,
I strongly recommend a very useful program that makes it much easier working with songs/styles on/to your SD-card, the cardreader connected to your computer and the KN7000. This software was special made for this kind of file-handling, by our SZ-member Thomas Konig, called: Technics KN7000 SD-Card-Tool. You can download it from: http://www.thkmcs.de It's free too
Greetings,
Cees
