The Casio GP-310 Celviano Grand Hybrid Digital Piano is designed for players who want the touch, sound, and presence of a grand piano, with the convenience and reliability of a premium digital instrument.
Developed in collaboration with C. Bechstein, the GP-310 features Casio’s Natural Grand Hammer Action Keyboard with full-length wooden keys. Unlike standard digital piano actions, each key moves with a true grand piano-style hammer mechanism, giving the player a more authentic sense of weight, balance, and control.
The GP-310 is powered by Casio’s AiR Grand Sound Source, offering three distinctive grand piano sounds: Berlin Grand, Hamburg Grand, and Vienna Grand. These tones give players a choice of character, from clear and elegant to rich and powerful, making the piano suitable for classical, contemporary, teaching, and advanced home practice.
To create a more realistic acoustic piano experience, the GP-310 includes detailed resonance and mechanical modelling such as String Resonance, Damper Resonance, Hammer Response, Key-Off Simulator, Damper Noise, Key-On Action Noise, Key-Off Action Noise, and Lid Simulator. These details help recreate the natural behaviour of an acoustic grand piano.
The Grand Acoustic System uses a powerful 3-way, 6-speaker design to project sound upwards and downwards, creating a more spacious and immersive piano tone. With 256-note polyphony, expressive pedals, built-in recording, USB audio recording, headphone mode, duet mode, and Concert Play, the GP-310 is well equipped for serious practice, performance, and home enjoyment.
The Casio GP-310 is ideal for pianists who want a premium digital piano that feels closer to an acoustic grand, but without tuning, humidity concerns, or the space requirements of a traditional grand piano.
