Vintage Synth Repair

Ok, then with a TP8, it leaves the possibility that the replacement mono pressure strip was thicker, preventing the second contact from making, unless the key is struck with enough force to compress the strip and make connect with the second contact. The second contact should close before the you hit the down stop felt, which in this case is the mono pressure strip.

Since there is no calibration, as every thing is fixed on a TP8, and all velocities are mapped in software, I also assume that you tried different velocity setting like hard and soft with no joy.

Another possibility would be a bent key frame, which I have seen on a TP10 many times, but this too is unlikely, as you would have to have severely damage it.  But you would know if it was damaged, as it takes a lot of force.   And a TP8 has a plastic frame, so bending equals break or just flex.

Which takes us back to the replacement strip is thicker, or the old strip was not completely removed and the new put over. I would look at and end key with velocity mapping set to the softest setting, depress slowly and observe when it sounds and when it touches the strip.  If there is a contact diagnostics, all the better, as you can see when the first(upper 3rd) and second contact(lower third of depression) make contact. The closing of the second contact causes a note on.  It must make before the key his the strip.  

I would phone or email Kawai on the diagnostics.

It had been one of the more supple  and responsive keyboards now it feels just plain wrong. Is there a  diagnostic or calibration page for recalibrating the keyboard? I could  take it back where it was for the last many months but that feels wrong  too.
