Just wondering, if the OS are up to date, is it still nessesary to
reinstall the OS, is'nt it enough to replace the .pat files with the
originals to get it load default settings for the style?
Maybe I'm wrong, because when load a style I thought all settings is
usually following the .pat file?

Btw, I think Ketron are very well allround balanced compared to many
other brands who often sounds like a totally different keyboard ( or
"band" if you like ) after loading a new style.
