The GP-310 is the Perfect Combination of Innovation and Tradition. From the moment your hands touch the keys, the GP-310 Grand Hybrid delivers the authenticity your performance demands. Developed in close cooperation with C. Bechstein to achieve a stunning re-creation of string and damper resonance, mechanical noises, and other subtle nuances, this one digital piano conveys the experience of owning three of the most outstanding pianos on the planet.

The Casio GP-310 Grand Hybrid is equipped with a specially designed 6-speaker amplification system that re-creates the 3-dimensional sound field created by a real acoustic grand piano. The top speakers replicate the sounds you’d normally hear rising upwards, and the downward-facing speakers mimic the sounds you’d normally hear from below the soundboard. Whether you’re performing or listening, the GP-310 sounds full, rich, and natural; while new EQ options give you the flexibility you need for recording and larger-scale performances.

The Natural Grand Hammer Action keyboard is spot-on. The vertical path, weighting, and pivot points of its full-length wooden concert grand piano keys are virtually identical to that of a real concert grand, and the keys use the same materials and processes as a C. Bechstein concert grand piano.

Casio’s Grand Pedal system continuously senses and detects the position of the damper pedal, fine-tuning the volume and note length depending on how much you depress the pedal. For performances that use the soft pedal, changes in volume and sound characteristics are extremely natural, enabling you to deploy a wide range of expression when playing softly.
