You make excellent points, Frog.

If I was listening to a recording of a piano player, on a digital, I would be hard pressed to tell you what kind it was.

I'd be more likely to be able to tell the difference between an acoustic and a digital, but even then, it would be tough, depending on the quality of the digital and the condition (tuning, voicing) of the acoustic.

Put these instruments in a band setting or even played along with an MP3 or SMF, and things would get even murkier.

Then mix in the various player techniques...

I do know when I "like" a piano sound.,,,what it's from matters not.

I like the sound of the default V-Piano, but to tell it apart from an RD, or a CP, or a Korg especially in a recording...it'd be tough.
