I suppose I shoulda said this was and upright.. just in case anyone was in doubt. The first answer that came in was really correct... even tho I think he (Doug) was refering to a grand. The problem was jack return springs. They were too strong. Normally on soft play a player doesnt always get to the bottom of the key stroke,, lots of actions handle this pretty gracefully as the back edge of the jack gets out just far enough that the knuckle can push it out of the way if it needs too. In this case the jack was designed such that almost all of its movement was in the last tiny bit of key movement so there was almost no help from its basic position at almost full key stroke. This coupled with very strong return springs actually caused the pianist to end even further away from full key stroke when playing soft (you could really feel this in the "heavyish feel" of the action) So the jack wouldnt clear the knuckle and it would blubber. If you forced the key down to the bottom all was well, but then doing this while playing made it next to impossible to play really softly So.. all the springs were removed one by one and eased. What amazed me was how much lighter the action felt. I shoulda taken downweight measurements.. and next time I will.. grin. Anyways.. Nice call Doug !
