All the Styles from the previous range of Technics keyboards (KN2000,3000,5000,6xxx) plus some styles from the KN2400/2600, were originally available on the now defunct Technics website, as free downloads.
When the website closed, I contacted Panasonic and obtained permission to add these styles to my website. They are still available, as a single download in '.sdb' format here : http://www.willumspages.co.uk/page8.html
When downloaded, they can be transferred to an SD Card, using the Panasonic 'Song Manager' program, as described on the web page. The download also includes some new 'World' styles.
