Anyway... it works !!!

Ah, good solution, 88 parts instead of 176. And also good there are different existing solutions to choose from.

cheers

Nice find, thank you! It shows, that Casio is using one dual-sensor at the hammer and a separate mono-sensor under the key. I assume all velocity-sensing is done just with the dual-sensor, because every other combination would need a calibration per key.

If I remember correctly, I've never seen a separate mono-sensor on Kawai's triple-sensors technology. Are they doing it the same as Casio?

Thanks

I would also like to know more specifics about this.

What i do know is, that the "middle" sensor (the one absent in 2-sensor keyboards) enables fast repetitions of the same note, since the key doesn't need to be completely releasled before playing it again. That's the biggest difference.

Yes, that is how triple-sensors "logically" work. But does this "mechanically" mean, that the key has to be in  contact with the rubber triple-sensor continuously, while doing fast repetitions?

i often read about triple sensors the last times. Does anyone know, how these are technically designed? Are they also these common rubber (or silicone?) knobs, just with 3 contacts instead of 2 inside? Are they all the same from one factory or vendor-specific?

Thanks
