Hi Marek

A flash memory that holds from 50 big to a maximum of 120 smaller flash styles is much more than most keyboards have. Yamaha could have delivered the PSR9000 with an empty flash memory and 145 extra styles on diskettes. Instead they have chosen to put 85 of these into the flash memory and only provide 65 on diskettes. If you want to have all the flash memory free for your own custom styles, all you have to do is back up the internal flash styles to 2 diskettes. They can allways be played direct from disc.

Regarding fill-ins and style change: As I see it from reading the manual (I have not yet received my own PSR9000), you can press one of the fill-keys marked with an arrow. This should give you a fill-in and change the style to the next variation, up or down. However, you can not go directly from variation A to C or B to D this way.
