Hi Stéphane More parts of the puzzle to think about eh ? And this question was a fun one for sure. To be honest I havent really thought about exactly this question before. Perhaps if you sample some of our now standard parameters we might be able to see into how this may or may not fit into this whole question of ratio and hammer mass. If you could give us the SW's, FW's WW's, KR, UW, and DW on say 10 sample keys we might have some fun with this one. And if you also could measure how far the hammer travels for 5 mm key travel (be very very accurate) that would be nice as well. I'm not so sure I'd buy into this being a voicing problem right off. I mean if the extremes are so very good then I have a hard time understanding that the hammers elasticity is involved. But I will ponder what others say with interest.

Very soft playing is fantastic, very loud also, but progressively crossing from soft to loud happens to be difficult to control, as sound gets loud too quickly, which is musically not desirable at all). > How would you all cure this problem ? > > Thanks to all for great expertise. > > Stéphane Collin. > -- Richard Brekne RPT, N.P.T.F.
