Hi,
I have that problem, also. I don't think it is an electrical fault at
all. I think the issue is mechanical. For me, the pads/contacts work
fine. I believe the key mechanisms can not depress the pads sufficiently
well. For me to use the keys, I have to press very hard, at the rear end
of the keys, near the fulcrum. I haven't had time to investigate
further, though I assume there is a fault with the mechanism house, such
that the fulcrum is displaced in some way.
That probably doesn't help very much, but some people may feel better
knowing that 'we are not alone'.
Cheers,
Oli

While with other keys it's a case of adjusting the pressure on the note. The previous owner said they probably need cleaning (since this is a common Polysix thing). I tried cleaning with a pencil(rubber)eraser and alcohol, but no succes yet.

And that during the delay it builds up the amount of electricity before it can be passed on to make the connection so you can hear the note. (sounds logical)
