Aftertouch

[Stéphane Collin]

Hello all.

I like to regulate after touch by feel.  Not enough after touch gives a concrete landing feeling.  Too much after touch gives a no timing control feeling (the finger information of hitting bottom of the dip comes too late against the sound).  Same for backcheck heigth : too high gives a concrete landing feeling and can be noisy, too low gives a butter landing feeling and doesn't repeat well.
But I took the lesson, when I'm happy with a particular after touch (which I realise when a whole section is done) , I'll use your intelligent systems to duplicate it accurately.
About the Wurzen punchings, I totally agree about the precision regulation thing, and the energy thing, but still feel that on certain pianos (I suppose not the loudest ones) it can be too noisy and tends to give a typewriting machine feeling.  I suppose also that the global case sturdiness comes into play here.  Could it be that we should adapt the front rail punchings to the string tension level, the hammer felt density and weight, the belly rigidity ?  One thing is sure, when it feels good, it feels good, and a huge majority of players will agree on this.

Best regards.

Stéphane Collin.

  I use a .030 punching to set uniform aftertouch.  Seems to be about right.  Cut a .030 card punching so that it can be slipped onto the front rail pin without lifting the key.  With the .030 card inserted adjust the dip so that the hammer just lets off with light pressure.  When you remove the card you will have adequate jack clearance from the knuckle which is really what aftertouch is all about.
