The Celviano Grand Hybrid GP-310BK blends innovation with traditional. From the moment your hands touch the keys, the GP-310 Grand Hybrid delivers the authenticity your performance demands.

Authenticity Begins at the First Touch
The Natural Grand Hammer Action keyboard is made with full-length, wooden, concert grand piano keys, using the same materials and processes as the C. Bechstein concert grand pianos. A keypress sends a hammer along the same vertical path as a grand piano, with the same essential weighting and pivot points, resulting in a true and uncompromising piano touch. The GP-310 features an enhanced touch response algorithm that allows for an even more accurate response. Players will feel more control with a softer touch, enabling flawless expression of the most subtle of performances.

Three Legendary Grand Pianos
Casio’s AiR Grand Sound Source provides not just one, but three of the world’s finest grand pianos. Dubbed the Berlin, Hamburg, and Vienna Grands, each one is the result of countless hours of precise analysis and study of their unique characteristics. They are faithful and expressive recreations of these distinctive pianos, with the Berlin Grand sound developed in collaboration with C. Bechstein. String/damper resonance, mechanical sounds, and other subtle nuances complete the experience of owning three of the finest pianos on Earth. The GP-310 enhances the sound of these sought-after instruments with longer, more natural decay than its predecessor, ensuring each sustained note tells a complete story.

Grand Acoustic System
Using an exclusive six-speaker amplification system, the new Grand Acoustic System reproduces the three-dimensional sound field generated by an acoustic grand. The top speakers present sounds normally heard rising upwards, and the downward-facing speakers present sounds heard from below the soundboard. This simulation fills the room with rich, complex sound, reaching both the performer and the audience. The GP-310’s speaker system is more powerful than its predecessor, with larger drivers making effective use of the powerful built-in amplifiers.

Under The Lid
The speaker system reproduces deeper, richer bass tones while enhancing the clarity of mid-range and treble frequencies. When the volume is adjusted, each speaker is automatically optimized to strike the perfect balance you'd expect from a meticulously maintained grand piano. New equalization options allow greater flexibility for recording and large scale performance. Now, you can choose to either maintain the pure sound of the six-speaker Grand Acoustic System when connecting to the line outputs or headphone outputs, or to hear the sound from the speakers exactly as it's being delivered to the line outputs, minus the equalization that optimizes the sound for the Grand Acoustic System. You can also choose to disable the speaker system entirely, even without headphones connected. This solution is ideal for music labs or other educational settings, where the line outputs are used to connect to student headphone interfaces.

A Soft Spot
The all-important soft pedal is essential for accurate dynamics, not only in volume, but in tone. The new GP-310 improves the effect of the soft pedal by adjusting the changes in both volume and tonal color based on the strength you use to strike the keys while the pedal is pressed.

Harpsichord
An enhanced harpsichord Tone has been added, including the distinctive "key-off" sound that occurs when lifting your fingers from the keys.

Striking a Balance
A longtime favorite feature for classical players, Concert Play gives you a starring role playing with a symphony orchestra. Now, you can fine-tune the volume of your piano part, ensuring you are right where you want to be in the mix. This adjustment is also available while playing along with the built-in Song library.

Seeing Is Believing
The high-contrast display on your Grand Hybrid features an inverted color scheme, allowing for easier reading from further distances and wider angles. The overall brightness is now focused on the text, leaving the rest of the display darker so you can focus on your performance.
