I gotta confess that, other than the keys, the S900 is a VERY hard to beat arranger at it's price point.

And you are already familiar with the 'Yamaha Way'...

Backward compatibility with everything you have already done is a STRONG plus point, zuki.

The only reason I'd counsel going to Roland is if you ADORE the sounds and styles, and can't live without them (or you need 76, which you've done OK without so far)...

But you've got to sit at one for a few hours to know that. Don't listen to ANY of us... Go and PLAY your choices, and make your mind up then!
