Do different reface lines have different velocity sensitivity?

I have a Reface CP and an YC (also, a PSS-A50, which I read has the same keybed as the reface lines). Both the PSS-A50 and the YC can be pressed extremely lightly (while the finger is resting on the keybed I gently start pressing down the key) and no matter how light I try the keyboard registers a note. But with the CP, it's a little different. I don't get any sound given the same amount of pressure. CP seems to like an initial 'attack' (even, a light attack) to get a sound.

With the speakers being on the quieter side the click noise of the keybed always seems a little loud and because of this, if try to play lightly and I sometimes hit a 'silent note' ( https://www.yamahasynth.com/ask-a-question/any-way-to-set-sensitivity-of-the-reface-cp-keys).

I'm still enjoying all three keyboard the same but just wondering if I got a 'defected' CP.

Thank you!!g
