A bit. And deepening the aftertouch.  A b= it. In fact, that's how I do the adjustment sometimes--- by feeling the aftertouch increase and turning the glides past the "no= rmal" point until the notch, or aftertouch, gets a little crisper and f= eels right. A quarter turn is a fairly big adjustment. Really? OK. Then a 1/5 turn. <g>  Any thoughts why this works? Lotta thought, no clear answers. Lotta skeptical laughter and proto-= derision when I tell other techs that I do this "extra-tight" bedding in flexible-frame Asia= n pianos. Then they try it.  It just adds so much subtle resonance in t= he piano, especially in the so-called killer octave area to the top of the p= iano. Don't scoff until you check it out. I'd think a more-solid contact with the keybed would reduce energy loss an= d improve sustain. I think so too; my more engineer-type colleagues & friends don't= buy that, but I really don't care why it works right now; it'd be interesti= ng at some point to know why, but not necessary, for me, at any rate. <BLOCKQUOTE>----- Original Message ----- From: David Andersen <mailto:bigda@gte.n= et>   </BLOCKQUOTE></BLOCKQUOTE>4) bed the keyframe, then add an extra 1/4 turn t= o each glide bolt.
