Casio GP400 Black Digital Piano
Collaboration with C. Bechstein
C. Bechstein has 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 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.
Genuine responsive action of a grand piano
Casio and C. Bechstein. They both know that the way a piano feels to play - it’s a deal breaker. So you’ll notice the subtle touches on the Casio GP400 that make it a privilege to play. The 88 full sized keys are made from high grade Austrian Spruce. The very same you would find on the revered C. Bechstein concert grand pianos.
The beautifully weighted keys also connect to real key hammers. These give you the most distinguishable and responsive feel when you play. Casio made sure the construction and action of the hammers follow the same principles of those found on grand pianos. The authentically weighted keys and grand piano action result in the nuances and expressions of your playing all being there, right where you expect them.
Grand acoustic system
Using an exclusive six-speaker amplification system, the 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.
Transport your performance
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, 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.
