something about aftertouch........

[David Love]

That someone would be me and you miss the point.  Andre argued that to
change the feel you could change the aftertouch.  I would argue that the
aftertouch is as you say, the function of a properly regulated
action--though you can adjust the amount of aftertouch by altering dip
or blow.  At any rate, the idea of changing the feel at the bottom of
the stroke by artificially changing aftertouch seems counterproductive
as it alters action performance.  Changing to a more forgiving punching,
if that's what it requires, makes more sense.  Making an issue about
what "normal" means misses the whole point.

In this case, and with someone with this particular need, even
considering that the aftertouch would be somewhat less precisely
defined, setting normal aftertouch with a softer punching would be
preferable to setting excessive aftertouch with a firmer punching both
for accomplishing the goal of a softer landing and for performance
reasons. But, you are right, we do have a choice.

Of course the problem with concepts like <<normal aftertouch>> is that 
in reality they correspond to diddlyin the real world. The degree of 
Aftertouch resulting from the various combinations of keydip/letoff/and 
blow outthere in practical use in effect defines the window for 
aftertouch so wide that the use of the word <<normal>> in thisconexion 
becomes rather a misnomer.

Inside the working parameters of what that window */does /*define 
however, it is an open question whether or not a softer
punching and less aftertouch would be preferable to a harder punching 
and more aftertouch.

And, as it applies to these particular <<harder>> punchings one simply 
has to take into consideration some factors that have prior to their 
advent been relavant.

1. The kind of hardness that results when the differing types of 
resiliency are figured in.
2. The increased sideways stability to the key the Oorebeek punching
yeilds
    -- less wear on key bushings
    -- just that much more of the finger energy delivered further up the

chain
3. The change in finger input vs hammer output.

to name a few important points.

There are always tradeoffs. And yes... we do have choices about these 
and indeed about whether or not we want to even acknowledge where some 
of those tradeoffs lie or not. IMHA, I try to find what the pianist is 
most comfortable with, responds best too... and drop any pre-concieved 
ideas of my own as to what is <<thee correct way>> of going about doing 
things.
