The CELVIANO Grand Hybrid—born of Casio’s original vision of researching and analyzing three grand pianos with long histories in minute detail and integrating the findings with Casio digital technology—has undergone further evolution. Taking into consideration the viewpoints of professional pianists as well, Casio has taken the greatest level of care in developing the model’s performance as a piano necessary for making progress in actual piano playing technique, down to the subtle nuances. Features include enhancements to the sound source’s chord resonance, acoustics that reproduce the sensation of the performing experience more powerfully and dynamically, and more natural variations in volume and tone quality obtainable by controlling the force with which keys are pressed.
