Collaboration with C. Bechstein

C. Bechstein have been one of Europe’s most important makers of grand and upright acoustic pianos for over 160 years. Their grand pianos have been the first choice for the world’s most famous composers and performing artists, from Franz Liszt to Bob Dylan. C. Bechstein worked closely with Casio to ensure that the key action in the Celviano Grand Hybrid Series responded as closely as possible to the key action in one of their own famous grand pianos. Similarly, the samples used to create the GP-Series’ piano voices were taken from C. Bechstein’s world-renowned D282 Concert Grand Piano. This collaboration between Casio and C. Bechstein has led to a digital piano that perfectly combines tradition and innovation.

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; resulting in faithful and expressive reproductions of these distinctive pianos. The Berlin Grand produces a balanced, elegant sound that's ideal for playing impressionistic music. The Hamburg is loved by pianists for its wide range of expression, delivering a brilliant and rich sound this piano is well suited for various playing styles and genres. Finally, the Vienna Grand is noted for its impressive low range, great for both soft and vigorous playing, an ideal instrument for classical music.

Natural Grand Hammer Action Keyboard

From the moment your hands first touch the keys, the Grand Hybrid delivers the authenticity your performance demands. The new natural grand hammer action keyboard is constructed using full-length wooden concert grand piano keys, with the same materials and processes as the C. Bechstein concert grand pianos. Each keypress sends a hammer along the same vertical path as a grand piano, with the same essential weighting and pivot points creating an expressive and uncompromising piano touch. Complete with acrylic white keys and phenol black keys, the GP400 feels familiar to play and ensures you feel comfortable during every performance.

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.

Hall Simulator and Listening Position

The GP400 features twelve types of Hall Simulators; 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 you can simulate the experience of hearing the piano from a seat in the audience, as opposed to the playing position, allowing you to hear your music from a whole new perspective.

Five Year Warranty

This Casio product comes with a generous five year warranty. This protects your piano in parts and labour costs for any manufacturing fault. This is an ‘on-site’ warranty, so a registered technician will come to the piano’s residence for any repairs.
