--------------------REPLY TO RICHARD WEST POST-----------------

Those are great questions Richard. Bring them all to the CAUT Forum where we
can get into them much more thorougly and with several opinions aired.
However, just to comment briefly about actions varying. Steinway has for years
slid their hammer action on the key frame to accomodate strike point, creating
pianos with different key ratios. My suspicion is that the varying key ratios
created much less problems in the "good old days" because hammers were
lighter. Unfortunately, a heavier hammer is not so forgiving to pianos with
"leverage" problems. However, this is just a beginning to what should be
discussed.

See you in Albuquerque.   Ken Sloane, Oberlin Conservatory

PS  Steinways new unified action fixes key ratio.
