Thanks for all the responses. I do think that the keys and maybe the rail are resonating. Softening knuckles, whippen heels, and key-end felt (thin bushing cloth layer then regular layer both glued on front edge only) will probably help a little. Anyone ever try VS on knuckles or is needling and suede brushing the leather all that I can do? Perhaps that felt under the keyframe reduce transmission to the keybed drum (it really resonated with a knuckle thump) will help.
