The Perfect Combination of Innovation and Tradition.
Since 1980, Casio has been creating musical instruments using constantly-evolving technology. Today, players of all levels enjoy Casio instruments at home, on stage, and in the studio.
For over 300 years, the piano has been embraced around the world as a vehicle for artistic expression. Its design has evolved through time, but the fundamental structure is still true to tradition.
Casio’s vision is to bring the piano experience to the next level by applying its technological expertise, and to create an instrument that would thrill the most demanding and traditional pianist.
Now, Casio begins a new chapter in the rich history of piano with the CELVIANO Grand Hybrid.
Authenticity Begins at the First Touch.
From the moment your hands touch the keys, the Grand Hybrid delivers the authenticity your performance demands. The revolutionary new 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.
Three Legendary Grand Pianos
Casio’s new 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 having been 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.
Grand Acoustic System
Our hearing goes beyond simply left and right, and we can detect the origin of sound in all directions. 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.
Resources
AiR Grand Sound Source
The CELVIANO Grand Hybrid incorporates AiR Grand Sound Source, a newly developed system using CASIO’s state-of-the-art sound technologies. It includes many impressive features. Multi-dimensional Morphing delivers smooth changes between soft anf strong playing. Acoustic Simulator reproduces the characteristics of sounds produced by acoustic grand pianos. The authenticity generated by the AiR Grand Sound Source ensures a pure piano experience.
Multi-dimensional Morphing
On an acoustic grand piano, the volume and quality of sounds change from the time the keys are struck until they die away. CASIO’s Multi-dimensional Morphing technology enables natural,smooth transitions in sound volume and tone based on the power of the keystroke. This technology contributes to more expressive performances.
Acoustic Simulator
Resonance System
The various types of resonance in a grand piano are crucial to the playing experience. The CELVIANO Grand Hybrid incorporates String Resonance, which exposes the harmonic relationships between various strings when keys are struck. Also Damper Resonance reproduces the resonance occurring when a damper pedal is pressed. In the case of the GP-500BP, GP-400BK, Open String Resonance and Aliquot Resonance add realism. CASIO’s Resonance System reproduces the resonance of both the strings and sound board of a grand piano by selecting, controlling and synthesizing according to performance conditions.

Hardware Resonator
The unique, newly developed Hardware Resonator synthesizes Damper, Open String and Aliquot Resonances to reproduce distinctive, individual sounds for all the respective 88 keys.
Action Sound System
A grand piano also generates several types of mechanical sounds, which are an important part of the playing experience. CASIO has sought to provide a more realistic simulation by reproducing the sounds of these mechanisms. Four types of operating sounds are included, and the volume of each can be set independently or turned off.
*Pedal Action Noise, Key On Action Noise and Key Off Action Noise are incorporated in the GP-500BP, GP-400BK.
Key Off Simulator
The lengths of the lingering sounds produced by a grand piano vary depending on the speed at which players release their fingers after pressing the keys. In a similar fashion, CASIO’s Key Off Simulator controls the length of these sounds based on the key’s release speed. This enables players to express delicate nuances when playing staccato and legato.
Slow key release
Long lingering sounds
Fast key release
Short lingering sounds
Hammer Response
The timing of a grand piano’s sound varies subtly depending on which keys are being played, even when the keys are struck with the same force. To achieve optimal authenticity, CASIO has installed appropriate settings for each of the three grand piano tones. The sound production timing can also be adjusted to suit the player.
Grand Pedal System
By continuously sensing and detecting the position of the damper pedal, CASIO’s Grand Pedal System enables fine-tuning of the damping volume and note length depending on the degree of pedal depression. In addition, the Half Pedal Position function permits adjustment of the depression position at which the damping effect comes into play according to the player’s preference. The Action Sound System’s Damper Noise and Pedal Action Noise features, in the case of the GP-500BP, GP-400BK, reproduce even subtle operating sounds like that experienced with an acoustic grand piano.
Grand Acoustic System
CASIO has developed a new dedicated speaker system for the CELVIANO Grand Hybrid that reproduces the characteristics of sound emanating upwards and downwards from an acoustic grand piano. The four-channel audio system incorporates six speakers, carefully positioned in a structural design that releases sound outward from the interior of the body. The system delivers the same sound field experience a player would enjoy while playing an acoustic grand piano.
Adjustable Lid Posiotion
The CELVIANO Grand Hybrid’s design includes a top panel that can be manually raised and lowered. The lid’s position not only physically affects the sound coming from the upper speakers, but also works in conjunction with the “Lid Position” setting to accurately duplicate the characteristics of the adjustable lid on an acoustic grand piano.
Hall Simulator & Listening Position
Twelve types of Hall Simulator are included; each one based on careful analysis of the acoustic characteristics of a world-famous concert venue. Each space has a total of four Listening Position settings. For example, the pianist can simulate the experience of hearing the piano from a seat in the audience, as opposed to the playing position.

Lid Simulator
The volume and timbre of sound produced by a grand piano change depending on the degree to which the lid is open or closed. The Lid Simulator simulates these acoustic effects digitally. Pianists can select among four settings for opening and closing stages and enjoy playing music with the piano sound effect of their choice.
*The Lid Simulator’s setting value remains unchanged, regardless of whether the piano’s top board is open or closed.
The 4 stages of a grand piano’s lid opening and closing have been investigated and imitated.
Volume Sync EQ
Volume Sync EQ is especially useful for quiet playing at home and other times when you want to keep the speaker volume low. This function balances the sound at low volumes by adjusting the sound quality in the low and high registers. The result is a constantly pleasant playing experience, no matter where the volume is set.
When playing at low volume
When the piano is played at low volume, natural sound is maintained through compensation of the tone in the low and high ranges.
Headphone Mode
Headphone Mode automatically creates a spacious sonic image while wearing headphones, recreating the feeling of playing an acoustic piano. With the experience of wearing headphones significantly enhanced, pianists can enjoy playing naturally and feeling the sound field of a traditional grand piano.
Natural Grand Hammer Action Keyboard
For an authentic piano touch, CASIO has developed a new keyboard system called the “Natural Grand Hammer Action Keyboard”. This keyboard system features full-length wooden keys as well as hammers that follow the same path of motion as in a concert grand piano. CELVIANO Grand Hybrid features keys that are manufactured using exactly the same materials as acoustic grand piano. Careful attention is paid not only to finish of the surfaces of the keys but also to the quality of the wood employed for the key beds. This combination of an outstanding action mechanism and superior-quality key materials further enhances the sensation of playing an acoustic grand piano.
1. Original Tri-Sensor action mechanism
The core of CELVIANO Grand Hybrid’s keyboard performance is created by CASIO’s proprietary action mechanism. This mechanism includes a hammer movement modeled from a grand piano and three sensors, which accurately capture a performer expression from the keys. Since there are no physical strings, CASIO’s action is able to exceed the performance characteristics of a grand piano, providing superior playability that enables pianists to perform such actions as trills and repetitive notes with ease.
2.Keyboard surface materials
The use of acrylic for the white keys and phenol for the black keys — the same materials that modern grand pianos employ. This creates a welcome and familiar touch. Pianists will feel comfortable and confident on the keys of CELVIANO Grand Hybrid.
The keyboard is made of the same high-quality Austrian spruce as the keyboards on C. Bechstein grand pianos. Careful attention is paid to drying and processing of this high-quality material before keyboard construction begins.
3. Fulcrum distance from keys
The position of the fulcrum with respect to the keys is exactly the same as with a grand piano. This contributes to stable playing performance, since the touch is never heavier or lighter depending on the position at which a finger strikes a key.
The keyboard is developed to ensure superior piano performances by considering each of the 88 keys independently and how they perform together as a single unit. Perfection of the keyboard is pursued as well through attention to such factors as load changes and key return speeds.
Comparison of keyboards’ dynamic characteristics

Precision load changes
The Natural Grand Hammer Action Keyboard is designed with high precision to ensure that changes in the dynamics pressure from the players’ fingers are similar to that of a grand piano. Players will have ultimate control over notes and dynamics.
Precision keyboard return speed
CASIO has conducted a thorough study of the speed at which grand piano keys return to their normal position after they are struck. This research has finally led to the development of a keyboard action with a consistent return speed and stable responses across the range of the instrument.
Concert Play
Playing with an orchestra is an extraordinarily thrilling event. Concert Play feature demonstrates orchestral performance for a pianist to enjoy an experience of playing as a soloist accompanied by a full orchestra. 15 pieces of music are built in. When you practice, a convenient playback function offers capabilities of play, pause, fast-forward, rewind and A-B segment repeat. Using a Slow Mode, the tempo of these pieces can be slowed to 80% of normal speed as needed.
Scene
Available with the GP-500BP, GP-400BK. This feature provides the most suitable sound environment to the music performers select to play. The Scene can be created by various combinations of tones, effects and reverberation levels. 15 different Scenes were designed as preset settings according to such themes as composer, musical genre and venue. Users can also customize Scenes and register up to ten of favorite settings.
Recording Functions
Audio Recorder
CELVIANO Grand Hybrid pianos have the ability to record performances on USB flash memory available on the market as stereo audio files (44.1 kHz, stereo .WAV format). Recordings can be stored or played back on a computer or transferred to CDs or other media. The piano’s built-in full playback function permits use of such features as pause, fast-forward, rewind and A-B segment repeat.
* Software available on the market may be required for producing CDs.
