The ability to set very close = letoff and the ability to control the action at pianissimo levels. This, to me, is the greatest limitation of the so-called "modern" = grand action......=20 Boy do I aggree with this. Kind of appropriate that this comes up = right now as well as I have just run into a pianist / piano combiniation = that quite obviously requires of me a level of pppp and control of that = which I simply can not regulate into the piano. I can push all the = borders to the limit and it still isnt going to satisfy him. He really = needs soft springy mallets. :)=20 I have been thinking of moving the capstan line in just abit. This = would drop the ratio a bit giving less hammer / shank speed for same = amount of key motion. It would also lessen DW tho... which could well = serve to give the opposite effect I want... but I'm tempted anyways. = Besides... just happens that the capstans on this Seiler grand are too = loose anyways.=20 What do you think ? I think you can try all that stuff but it won't make up for the fact = that the grand action is up-striking and you can only set let-off so = close to the string. From that point on the hammer goes into free-flight = and you must have attained sufficient hammer velocity to carry the = hammer through this distance and still impact the strings with enough = force to make meaningful sound. It's just very difficult for the pianist = to do this with consistent control. The vertical action, by contrast, does not have to fight gravity for = those last couple of millimeters of flight. (The Fandrich Vertical = Action was (is?) regulated with let-off at about 1.5 mm.) So, when I hear some say some grand action design can be regulated with = let-off right up to within 1 mm of the string line I at least want to = give the thing some thought. And one of those thought is, "I wonder how = this thing would work with a nice graphite-filled ABS or Nylon jack?"
