I can't see anything visually wrong with the keypad contacts. There
are two
pc contacts per note. One rubber keypad contact opposite the pc contact
extends just a hair more than its adjacent rubber keypad contact. How
does
this translate into detecting how loud to play a note and how do you
think
this relates to the note that is too loud?

It's a dual-contact pad. One of each pair should contact before the other.

This behaviour is what happens when the early contact fails, and the
late one does not. The controller sees nothing, followed by the late
contact, so it assumes a high-velocity key-stroke and plays full volume.

Fix or replace the early contact.


Isn't that interpretted as a non-key press, a dead note, second contact
only. I seem to remember simulating that, with placing a piece of paper
under the first contact.
