If this is a Baldwin with corfam instead of buckskin on the butt it could be the problem. Especially the black corfam was very compressive and would change let off position quite a bit from a loud blow to a soft one. If it has corfam it needs to be replaced, because it gets hard and noisy and keeps the piano from working well.
