Hi Ian,
I get what your saying about a Tyros 2 = S900.

Yamaha doesn`t want to compete with it self.

But with all the reported issues , I just wish that Yamaha had done a better job ,

They really don`t have to change from plastic buttons to rubber , not for the top 2 PSR`s.

They do have the sound , that much is certain , if they just had the quality.

I`m happy that you have had good luck with yours and I hope that continues as you might be just part of a handful happy owners,

Take care ,
Gary
