The free kn5000 styles on kn7000.com will only load into a kn7000.
If you have a 6000 or 6500 they are no use to you, so the 5000 reprise disks are still useful for those owners, particularly since they also have all 8 fills for each style included, which were not saved on the 5000, and each panel memory and style and all custom stylists containing all the original descriptions for those who used these to find their favourites. They were also optimised for bass lines and others in chord modify change for the transition to NX sound from pre-NX.
