The SD cards are the same. Why did you use the Songs/Styles/Sound? That's not the way the KN-X000 set's up the SD disk. Songs are in a different area than styles. You are limited to 99 folders of 20 songs, but you can put as many styles( file extension CST)on the SD disk as you have memory. The keyboard organizes the information for you. Why would you want to change it?
