<html><div style='background-color:'><DIV> Avery, The key dip/after touch should be the same throughout the piano. But MOST piano technical manuals, including Yamaha, call for three individual let-off measurements in BOTH grands and verticals for the bass, tenor and treble. Having said that, many techs DO use only ONE let-off measurement and leave it at that. Again, your call.

Obviously. :-) My question regarding your post of last night/yesterday is what do you do about key dip/aftertouch if you alter the letoff that much from bottom to top? I prefer to have a fairly consistent key dip/aftertouch when I can. Even on a vertical but ESPECIALLY on a grand! It just seems to me that a let off from bass to treble like you mention, would make that very difficult! Do you do the same thing on a grand? With the artists I have to deal with, I couldn't do that. Most of them would notice! JMHO. Avery At 02:37 PM 09/10/03 -0700, you wrote: >Dale, > >Thanks for your feedback on the let-off topic! I usually use my >aforementioned specs for older verts.
