CyberGene So, I think mapping between different piano actions (and using samples from one of them on the other one) is a non-trivial task which is even impossible to a certain degree.
Yes, rather impossible. Last week, yesterday and today I played another few different grands. They are all sooo different in many aspects including dynamics and response. Some are hard to get some 'passion' out of requiring effort. Some others are like Veyrons, like WHOAAAA! EASY BOY, EASY on that throttle!! Where a gentle to normal touch makes the roof plaster come down, so much output do they give.
As to dore_m 's (indeed interesting!) topic: in general people just don't know what they're talking about. Have no experience with actual pianos, room acoustics, and just blabber from some conception they have without any clue how they formed that conception.
And, generally, many don't know what a simple volume adjustment does to perceived dynamic range. When I use Modern U at a realistic volume setting (measured) then its dynamic range reminds of an actual upright. But of course if I turn up my amps beyond 1/3 volume, Modern U still plays very softly ppp but fff becomes speaker-breaking thunderous.
All of this needs objective benchmarks, measurements, and so on to take discussion, guesswork, and opinions out of the equation.
Cheers and happy thunders,
