Buying a S900 for a back up when you have a Tyros 2 is a good idea. But comparing a S900 to the Tyros 2 is not a great idea. I have both sitting side by side playing the same midi file or a style or live playing. The Tyros 2 has a much richer tone – I say it has class –
The Tyros2 is the one I sold my friend and the S900 belongs to me.

A N D I just love my S900, it does almost everything the Ty2 does – except it’s much cheaper -- but it’s still no Tyros 2.
