Casio’s Grand Hybrid Piano Experience

Designed in collaboration with renowned acoustic piano maker C. Bechstein, Casio’s Celviano Grand Hybrid GP-310’s astute combination of innovative and traditional elements raises the bar for today’s hybrid pianos. The moment your fingers alight on the keys, you’ll feel and hear the GP-310 Grand Hybrid’s definitive grand piano authenticity; and your performances will never be the same. Casio’s groundbreaking Natural Grand Hammer Action keyboard is made with full-length Austrian spruce concert grand piano keys, using the same materials and construction as C. Bechstein concert grands. A key press actuates the hammer along the same vertical path as a grand piano, with the same weighting and pivot points, resulting in true, uncompromising piano touch.

State-of-the-art AiR Grand Sound Source

Casio’s AiR (Acoustic and Intelligent Resonator) Grand Sound Source offers many impressive features and benefits, such as Multi-dimensional Morphing, which provides for smooth changes between soft and strong passages. Acoustic Simulator technology reproduces the characteristics of sounds generated acoustically by acoustic grand pianos. Harnessing and focusing the power of this state-of-the-art sound engine, the GP-310 delivers not just one, but three of the world’s premier grand pianos from Berlin, Hamburg, and Vienna. Each instrument the result of meticulous research and analysis of its unique characteristics, the Berlin, Hamburg, and Vienna Grands are faithful, expressive virtual incarnations of these distinctive pianos.

Three of the most outstanding pianos on the planet

Developed in close cooperation with C. Bechstein to achieve a stunning re-creation of string and damper resonance, mechanical noises, and other subtle nuances, the Celviano Grand Hybrid GP-310 conveys the experience of owning three of the most outstanding pianos on the planet. The GP-310 enhances the sound of these impeccable instruments with brilliant chord resonance and longer, more natural decay than previous-generation Celvianos, ensuring that each sustained note tells its own complete story. The GP-310 also gives you enhanced sensitivity and expression for pianissimo sounds, especially when at pianississimo and softer.

Natural Grand Hammer Action keyboard and Grand Pedal system provide authentic piano feel

The Casio GP-310 Celviano Grand Hybrid’s ultra-realistic 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. We play a lot of pianos here at Sweetwater, but we’ve rarely found a piano-playing experience like this!

Grand Acoustic System creates a stunningly realistic piano presence in your room

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.

Many of the keyboardists here at Sweetwater have fond memories of Casio that go all the way back to when we first started playing, and that's often kept us coming back for decades. Today, we're happy to point players to Casio keyboards, no matter how long they've been playing - even if they've never played at all. In fact, we've set up many beginners with Casio LK series Lighted-key models, and they've regularly raved about how easy these keyboards make learning. Likewise, several of the solo performers at Sweetwater swear by their fully loaded Privia and other advanced lines, which provide top-notch accompaniment and more. And if you stop by the Sweetwater Piano Showroom, we'll be happy to show you the latest Casio home piano - all providing amazing value and style.
