Most of the downloadable files that you will find in our website will be already converted
to the WK/CTK-691 series native .Zxx format.
This means that you will be able to upload them directly to your PC's
floppy drive or smart card (if you have an economical smart card reader/writer installed
in your computer). You can then remove the the card/floppy from your PC and plug it into your keyboard and use the disk/card button to upload the files without ever connecting the keyboard to your computer!
