I am not a pianist and don't have a real piano to play. In the following samples of Ivory Grand Pianos, I find the tone sharpens without accompanying increase in volume, too low in the key velocity range. They make the pianos sound clanky and unrealistic in what seems to be meant as below forte. I don't recognise the piece- does anybody? I was wondering, if people agree with me, if it is possible to adjust the output so that the softer tones are used comparitively more and those bright tones only in real forte in a more advanced way than just fiddling with the velocity response curves.
