Arbaz,
actually I did not say that. I wrote that I don't know if the PSR 2000 supports this feature. For what I know about Yamaha arrangers, they seem to have only a limited amount of memory dedicated to storing your own styles, so I have a feeling that you are not allowed to record very complex styles with a lot of variations.
Again, I cannot swear on this, because I have never owned a Yamaha arranger. I hope that an actual PSR 2000 user will reply to say the final word on this issue.
