Are you using the S910 with the Bose L1 Compact?
I'm still using the PSR3000 and in the mono mode the piano is terrible. In stereo on a larger gig it sounds just OK to me.
I'm very interested in the piano sound especially in mono because a lot of my gigs are NH's "mono".
How good is the piano in the S910? Is it from the Tyros series?
Thanks.
Peter
