Hi Nobby. Were these psr9000 styles converted from other keyboards or were they originally made for the psr9000? If they were converted maybe there was a glitch of some kind in the conversion process. I don't have either keyboard myself so I don't have any first hand knowledge. I wouldn't think there would be that much of a difference in the style structure between the 9000 and the 2000 but then again I could be wrong.
