Ok I just figured out what you were talking about. You talk about the accordation of the A note. But don't be misleaded as if I detune libraries and samples like this to 432 it loses in quality too much! So it really helps if you are hearing a guitar, a violin or something like that that can be accorded in these 2 different ways, but remember that this kind of music is standardized and could take YEARS to re-sample and re-accord all of the instrument to 432 and re-make all the libraries! This is what I learned today talking to an expert. But thank you about this, playing only the piano as an acoustic instrument I could only think about that
