Perfect combination of innovation and tradition

The GP-400 is the latest - and the most elegant - model in the CELVIANO Grand Hybrid lineup. Like the GP-300 and the GP-500 comes the GP-400 with the three historically popular grand piano sounds and the keyboard is made of the same high-quality Austrian spruce as keyboards in C. Bechstein grand pianos. The new look and haptic makes you feel like playing an ordinary piano.

Thoroughly refined sound and reverberation reminiscent of a grand piano

The AiR Grand Sound Source reproduces the same beautiful sound and rich reverberation as a grand piano.

Multi-dimensional Morphing smoothly transforms sound waves, and realizes tonal changes based on both time passage and intensity. Even during a gradual crescendo from pianissimo to fortissimo, the technology allows even and natural tonal changes.

Moreover, the String Resonance System, designed to deliver the string resonance of a grand piano, controls the amount and combination of resonance according to the playing situation. By producing reverberation that fits each of the 88 keys, the technology enables natural and comfortable performance.

By combining these two technologies, the new model offers the sounds of three grand piano styles. The Berlin Grand is known for its elegant clear sound and reverberation that gives each performance rich melodic color, while the Hamburg Grand delivers gorgeous power and strength with a lot of string resonance. The Vienna Grand provides calm bass with a solid feeling along with soft and beautiful sound.

Natural Grand Hammer Action Keyboard enables even more delicate expression

Grand Acoustic System generates a space of three-dimensional sound

Casio has developed a Grand Acoustic System that faithfully represents the sound of a grand piano as it emanates from above and below the soundboard. Through careful positioning of six speakers and the creation of sound pathways, the system delivers three-dimensional sound with tonal elongation, expansion and depth.

Special playing experiences made possible by a digital piano

Scene feature enables pieces to be played with the optimal sound

The Scene feature consists of 15 preset types for different composers such as Chopin and Liszt, as well as musical genres such as jazz and easy listening. The presets combine the best optimal tones, reverberation, and effects for the type of piece being played. Users can also create and save their own presets.

Concert Play offers an experience like playing with an orchestra

The spectacular sound of a live orchestra is recorded in a high-quality digital format. By playing the piano together with the recorded orchestra, users can enjoy the feeling of performing at an orchestral concert. The technology can also be used in practice, as it allows the tempo to be slowed, and also features rewind, fast forward, and repeat playback of A-B sections.

Hall Simulator provides the experience of performing in a special venue such as a concert hall

The Hall Simulator allows the pianist to enjoy the immersive sound found in different types of venues such as an Amsterdam church, or a classical concert hall in Berlin. Also, the GP-400BK enables users to switch between the Player's Position, which provides a sense of playing a real grand piano, and three types of Listener's Positions, which gives the pianist the effect of listening to the performance from the audience.
