and there you have it, Ad
With Yamaha machines a .sty file works in most of them and styles are readily interchangeable. Not quite so straight forward with Technics keyboards...
Technics keyboards are backwards compatible e.g. a newer model will accept style files from older models, but never the other way round...not without some work doing on it.
Try Gunnar Jonny's site at: http://home.c2i.net/gjgotaas/
for some Kn2000 style files.
