Hey Rikki,
Thanks for the reply.
In the options pull down menu, it gives me the option to save data as a set (ticked) or not (unticked). They then get saved as just a *.sty file (still huge though!!!)

When I try the converted style, it works fine, and there is only one style available to load, it does take a bit of time though which is also unusual.

I will investigate further from your suggestion that it might actually be saving the default Korg Set data as well as the converted style file..

If I have no joy, I might have some more questions for you if thats okay.
Cheers
Dennis
