Ron, Thanks for that resumed point of view, seem to meet what I suspect. Can you give a definition of action saturation ? I am unsure if it is the fact that the move of the key at a certain moment can't accelerate more the hammer and is it for limit in flexibility or because the key bottoms. if I believe the fact that the key can be made bottoming before the hammer have even start to move on certain actions (may be due also to lack of stiffness under the keybed), the hammer will still be driven by the key un flexing so when is the saturation occurring ? is it only tone saturation ? I like to see that like 2 different aspects. BTW, the piano hammer is may be tone of the fastest accelerated actions on earth, 0 to 40 miles/hour in 1/400 sec is faster than my motorcycle (that accelerates fast enough yet!) Greetings.
