Clavia Nord Electro 2, keyboard of 2007

[N_Cook]

Will not reliably switch or stay latched in piano or synth mode via the
select switch. I suspect the light action switch is too light. Easy
enough to remove the keycover and inspect the phosphor bronze action. Is
it just a matter of cutting back the spine of the keycap a bit , so the
action is farther removed from a hair-trigger situation? All clean and
tidy inside the switch.

I think cause or part of the problem is the metal casing of the top ,
containing the switches, has been bent,dished or flexed slightly. The
keycaps are then partially compressed by the metalwork. Some padding
washers will go in there, as any of the keycaps could be the next affected.
Also the wooden end cheeks are loose. Only 2 thin wood screws per cheek
, and the wood is now not holding the screw threads. Some bracing plates
will go in there with 3 woodscrews extra. Employing the old carpenter's
trick of the axis of the 3 screws all angled relative to each other so
they mutually anchor themselves in there, also allows longer screws for
the relatively thin wood available.
