You could import and convert styles from other keyboards, at least you could Roland styles.
However it is the only brand on which I ever had to worry about breaking keys. They were not that strong. I remember replacing several.
My friend DickieT bought a KN800 because I had one at the time. He left it in the trunk of his car and the plastic case melted. It still worked but it was really ugly.
I had 800, 1000, 2000, and 5000. I sold the 5000 to DNJ. Still selling him stuff.
