That's probably the best video demonstration of the keyboard's onboard Style Creator program I've seen. It clearly demonstrates just how many steps you must go through to make a good style, which, unfortunately, most people are not willing to take the time to do. Of course, there are more than 70,000 third-party Yamaha styles available today because of the individuals that did take the time to learn how to do this. My collection is now just over 55,000 style files, which has taken more than a decade to accumulate. Some are really bad, some are great and many are absolutely fantastic. A significant number of these styles came from the UK, therefore I must pay tribute to my many friends across the pond for their wonderful contributions to the world of arranger keyboard styles and music in general.
Cheers,
Gary
