Loss of pianisimo ? (heavy key press only to activate) on 2 keys. That
area schema/views not on elektrot. 2 contacts per key?, one worn or
dirty per key?




Nearly always due to dirty or worn key contact rubbers. These are
usually in octave strips available from the manufacturer.
Don't bother trying to repair these with paint etc. Really.
(Sometimes its just due to dirt - tobacco, pet hairs etc which can be
cleaned off)

Each key has 2 contacts, one hits the PCB before the other, the time
difference calculating the speed of impact, and thus loudness of note.



Gareth.

Assuming if not just grime, I have a large collection of zapper contact
sheets, to cut a couple of dimples from, and give them a go




No, no, no, no, no, no, no, no, no, no, no.
Really.


I knew that was going to happen.
