Has anybody tried to edit or create a style? I've just tried it and can't believe how unusable it is. The editor is a joke. It looks like it has been build 30 years ago and has never been touched since then. I really don't understand what I have to do to edit or create a style. The manual is no great help. There seems to be no way to make a style from a midi-file or from Yamaha-styles or other stuff.
