set letoff to get acceptable aftertouch?

[Richard Brekne]

Grin... ok... no begging. I just dissagree. Aftertouch in a grand is 
clearly a different puppy then what is loosely called aftertouch in an 
upright.  Heck the <<touch>> in the term should be nuf of a kicker to 
clue one in on that.  "Jack escapement" in both are quite similiar... 
but aftertouch, (in both cases if one insists on misusing the term in 
the case of the vertical) is quite a bit more then jack escapement. 
Which indeed is about the only thing they do have in common.

The academies and other resources cited make these distinctions for a 
reason, and it seems pretty clear to me what thats all about. I find it 
hard to understand how emphasizing a point the various academies for 
concert technician work themselves emphasize does them any disservice 
Paul. 

But no matter. Well wishes accepted and doubly returned friend Revenko ! 
Its perfectly ok to differ me thinks :)

     Quit begging! Just differ. The technical definition of aftertouch
    as the "distance the jack travels after escapement" (grands) or "the
    distance the jack has traveled" (uprights) is as easily applied and
    regulated for in both grands and uprights.? They are both the "after
    escapement" portion of key travel. The analogs between grand and
    vertical escapement/aftertouch (distance) are plain and useful
    whatever academy you're citing. The physical analog between the
    knuckle and hammer butt are clear, and the differences are, too. So
    too the family of regulations for them, although with different
    preferred emphases and order--key height, key travel, blow distance,
    and let-off. Other fine differences can be made with other
    regulations. Both the similarities and differences are useful tools
    to have. Too much emphasis on the differences to the exclusion of
    the similarities does a disservice to the Academy as a whole.

    Wishing you well!
