This is a tutorial covering how to load tones that were downloaded from the Casioforum site. I couldn't find instructions anywhere on how to do this. It took me forever but I figured it out. The user manual only shows how to get the USB stick to work on the board, Make sure you put the files in a MUSICDAT folder before loading it on the USB stick. You can make the MUSICDAT folder on your Computer or by formatting the stick on the keyboard.
