sounds reasonable to split aftertouch between blow and dip. Perhaps I should review my opinion about key dip as a constant. But an action is a system where everything depends on everything, so we need at least one constant, a fix point to start from. I was told that this starting point should allways be the keyboard with height and dip. If I got you right you do exactly that, too. But you re-regulate dip if aftertouch is uneven. <BR>
<BR>
I allways thought that no pianoplayer would notice a small difference in let-off. Thatīs the reason why I use let-off to alter aftertouch (without giving up my constant fix point key dip). But perhaps I am wrong in that point. And what is valid for the let-off should be valid for the dip too: small differences are not noticed. <BR>
<BR>
What I donīt understand: how do you change blow for a single key without altering the blow of the neighbour key? And does that not result in an unequal hammer line which looks not so fine? I know the trick to make an even hammer line by pressing the rest rail felt with a hot steel.<BR>

If I had to alter anything to <BR>> make the after-touch even while keeping the same key-dip, it would be the blow! <BR>> But I submit that keydip is less important than aftertouch. <BR>> At the very top of the line regulation, I alter keydip AND blow so that <BR>> aftertouch is identical. When doing this, I first set the keydip to a static <BR>> value and make sure all keys are equal. If, with an consistant blow, I have <BR>> unequal aftertouch, I will move the keydip as much as .010" and the blow as <BR>> much as .060" from the predetermined specs. The effect of splitting the <BR>> difference like this,(between the dip and blow) is to make all the irregularities <BR>> fall below the threshold of even the most sensitive pianists. <BR>> I have never seen any pianist notice .010" difference in keydip if the <BR>> aftertouch was even, but I have been called back for having less than 1/16" <BR>> difference between let-offs, (Ronnie Milsap is able to tell instantly if the <BR>> let-off is not exactly even, but he never noticed the slight difference in dip.)<BR>> Regards, <BR>> <BR>> <BR>> <BR>> Ed Foote RPT <BR>> http://www.uk-piano.org/edfoote/index.html<BR>> www.uk-piano.org/edfoote/well_tempered_piano.html<BR>> <BR><BR><BR>**************<BR>The year's hottest artists on the red carpet <BR>> at the Grammy Awards.
