You can't get the OTS settings with the PSR9000. You have to create your own I suppose. The CVP209 and PSR2000 have similar file systems. Thus the OTS settings for the CVP209 translate well into the PSR2000. I don't think the PSR9000 can have OTS embedded into the style. I think you need a separate OTS file.
You can still enjoy the styles, especially since your PSR9000 has some style voices that are missing in the PSR2000.
