Scott, My friend who was a skilled musician and knew his PC well, tried to convert the Kn6500 styles into his Yamaha psr740 had very little success.
From the Kn into the PC reworked in Cakewaklk, then to a disk, and into the Yamaha. It can be done but the feel was not there. They sounded OK, but not equal to his yamaha styles.
Having said that, pick a style and we'll both have a go at it. I have both keyboards as you know, and this could be fun.
Take care, John C.
