   Bill Garlick sets let-off by taking the hammer to let-off, and then rather
quickly, pushing through.  He lowers it until the hammer will not hit the
string from a quick note.   
   I have better success getting what I want by touch, and the easist way to
get the feel for it is to start from blocking, and gradually turn the button
down,  all the while playing as softly as possible.  There is a certain point
reached where, on an extemely soft blow,  you can still feel the hammer touch
the string before or simultaneously with release.  The optimum distance for
let-off is just beyond this,
and it is difficult to achieve a consistant placement here by anything other
than feel.
