Well, I can explain my choice 😀
Main mic is the player one, kinda makes sense if you sit in front of a piano:
"This is the most natural mic setup in the library and really does emulate the experience of sitting at this piano, with just the right balance of direct and room detail along with a natural stereo image. This is the go-to classical mic."
Then you definitely want to hear the soundboard:
"A unique perspective away from the hammers capturing only the piano's soundboard up close with a wide image, the tone is warm and immersive, a bit 'woody' with a broader hammer attack."
The mono one sounds very important:
"Positioned just above the action front and center, this mic captures everything, the warmth and detail all with a modern edge."
As for timbre, I've seen a description of what it does somewhere, so turned it a bit down.
And eliminated the pedal noise, that's really disturbing, the piano has to be in a very bad shape to make noises like that…
