1) Casio – Scaled Hammer Action

What is the best Casio hammer action in digital pianos?

Casio’s Privia Line features the innovative Tri Sensor Scaled Hammer Action II system for its more expensive console pianos (like the Casio PX-870) and the Smart Scaled Hammer Action Keyboard for its cheaper portable digital pianos (like the Casio PX-S1100).

Casio’s Tri-Sensor Scaled Hamer Action Keyboard is particularly impressive.  This key action system uses three sensors under each key to accurately capture the dynamics and subtleties of your playing. 

The scaled hammer action closely emulates the feel of an acoustic piano, with heavier resistance in the lower register and lighter touch in the higher register.  This provides a very natural and responsive playing experience.
