I think all piano voices on Yamaha arrangers do good for what they are designed: cut through the mix, you can’t hear acoustic subtle effects anyway.
But many are just too soft and with a narrow stereo image, at least with my Sennheiser headphones, especially the CFX.
Often, I want to play piano by itself, but then, some parameters need some tweaking to enhance realism.
I could post detailed values for each piano sound I modified, but in general,
I will boost Velocity depth around 73, Release to 27 ( damper felts don’t kill string resonance instantly),
Damper resonance 40, especially for high half of keyboard, lower the Reverb to 8,
boost Chorus to 12 ( real pianos are somewhere between recently tuned and due for tuning), and Eq settings to taste.
My best built-in piano sounds are from the Legacy folder:
Concert grand 000-122-001 ( the one most preferred with the recent blind test on this forum ),
PopGrand 104-005-001,
Warm Grand 000-114-001
Grand Piano 000-113-001: like a good upright Grand.
But my best expansion piano voice is the GranCoda Live, from a member on this forum ( FREE! ), with similar tweaks, of course!
Hope that helps,
Yvon
