Hi,
I've set mine up into folders on my sd card that match the keyboard ie 8 & 16 beat, 60's& 70's etc . I also created matching folders on my computer. I keep the individual .cst's that I downloaded from the kn7000 website in my computer folders. I've sorted them into ie 8 & 16 beat folder which contains sub folders for 16 beat ballads, 8 beat ballads, 8 beat rock etc. I can then manipulate and load them into the kn7000 in the configuration that I want. I've also located most of the duplicated styles. At the moment I'm creating a list of the style no's & types and their duplicates.
I've been using an inexpensive sd card reader for back up purposes, but the .cst's can be loaded individually into the kn via floppy disk and then saved in groups in kn to the sd card.

best wishes
Rikki
