Casio Digital Pianos - Authentic Sound, Modern Technology!
We are dedicated to the tradition of the grand piano and meticulously focus on the essence of the piano - its sound and touch. At the same time, we have introduced various features that enhance the charm of the piano through new experiences. Thanks to Casio's unique sound source technology, our instruments deliver delicate and rich tones. The acoustic system conveys an unparalleled feeling of authenticity, making you feel as if you have a grand piano right in front of you. The integration of physical mechanisms and digital technology ensures a response comparable to the refined techniques of classical pianos and complements the expression of musical performance with a special keyboard.
Furthermore, Casio offers a new perspective on piano enjoyment with innovative features that provide visual confirmation of your playing. Our instruments are packed with Casio's distinctive ingenuity and offer a unique approach to enjoying piano playing like never before. The AP-550 is equipped with a proprietary acoustic system and features the advanced sound source of higher-end models, allowing you to fully experience the fascination of the classic piano. With the AP-550, you can fully enjoy the expressiveness and joy of playing grand pianos with their rich heritage.

Classical and Modern United
The AP-550 belongs to the Classic series of the new Celviano models. The classic and minimalist design, available in 3 color variants, will delight piano purists. A clear function control and the innovative hybrid keyboard are rounded off by the balanced sound.
Sound Generation
- The Multi-Dimensional Morphing AiR Sound Source ensures natural resonances
- Discover how tonal nuances and timbre change depending on playing speed and touch thanks to Multi-Dimensional Morphing
- The String Resonance System provides complex and realistic resonance behavior - like an acoustic instrument
- Experience the authenticity of a concert grand piano thanks to our Mechanical Sound System, which simulates various mechanical noises of the instrument
- Switch between four different sound variations with the Lid Simulator, corresponding to opening and closing the grand piano lid
- Lossless Audio Compression ensures excellent audio quality
Impressive Variety
The digital piano, with its large body and complex structure, produces a rich and delicate resonance sound. Fine nuances of playing, resonances, and dynamic sound changes are reproduced authentically and faithfully. The AP-550 model also offers two impressive grand piano sounds through the "Multi-Dimensional Morphing AiR Sound Source" for a natural and fascinating playing experience.
From delicate touches that sound like a breath to dynamic and powerful expressions that convey the player's emotions, these instruments offer a natural, beautiful, and captivating grand piano experience.


Authentic Playing Feel
Casio thoroughly researched and independently developed the "Smart Hybrid Hammer Action Keyboard CELVIANO Edition" to optimize it for the AP-750, AP-550, and AP-S450. This advanced key mechanism takes into account the characteristics of grand piano keys and significantly influences the playing feel.
It combines physical mechanisms that use the weight of hammers, similar to grand pianos, with advanced digital technology that controls the playing feel and sound response for each key. This innovation enables expressive performances that faithfully respond to the pianist's emotions and adapt to different playing areas and techniques like a grand piano.
Unfolding Expressive Possibilities
Discover a new realm of expressive possibilities with the carefully crafted pedals of the AP-550. These pedals are designed to capture the authentic feel and nuances of a grand piano. The damper pedal not only sustains the sound but also reproduces changes in resonance and gently adjusts its effect depending on how deeply the pedal is pressed, allowing sensitive expression in your musical performance.
The soft pedal not only controls volume but also offers a more natural change in timbre and expands expressive possibilities in quieter passages.

Immerse yourself in a touch of sophistication thanks to the many small details that shine in gold and give it a unique impression. With a wonderfully rich, far-reaching sound, a touch directly connected to the expression of the player's emotions, and new features that create a new experience, you can enjoy the charm of the piano once again.
Comfortable and Stable Piano Bench
This piano bench offers high-quality features alongside its elegant appearance, such as sturdy legs with non-slip rubber, a smooth, precise spindle mechanism for height adjustment, and a durable, comfortable seat covered in corduroy. The sophisticated spindle mechanism with a double scissor system guarantees smooth and extremely durable height adjustment. Small details like rubber stoppers between the base frame and support frame clearly set this beautiful piano bench apart from others in this price range.
Headphones
The Pronomic KH-900 is a professional stereo headphone that combines excellent sound characteristics with maximum wearing comfort at a budget-friendly price. The soft, wide synthetic leather headband automatically adjusts to head size, ensuring a comfortable fit. The KH-900 features a wide frequency range from 15 to 25,000 Hz, delivering balanced, nuanced sound with brilliant, clear highs and precise, rich bass. Thanks to the low impedance of only 32 ohms, the KH-900 can impress with powerful sound and enough power reserves even on very low-powered headphone outputs, such as MP3 players or smartphones. The 3.5 mm stereo jack plug ensures excellent transmission quality. A 6.3 mm stereo jack adapter is also included.
Piano School
The instrument is introduced and explained to beginners in a playful, relaxed way. Starting with familiar, simple melodies up to two-handed playing of complete songs, various theoretical knowledge is also conveyed alongside. Reading notes, rhythm, dynamics, and much more are covered alongside the exercises. Additionally, the simple exercises guarantee quick learning success.
