Acoustic & Intelligent Resonator Casio PX 770 Digital Piano Instrument


Slim, stylish, and more fashionable than ever. The Casio Digital Piano PX 770 in black is fully equipped with a wide range of sounds to be explored. The Casio PX 770 allows you to take advantage of an incredible range of styles and genres from all over the world.

And thanks to the sleek and modern design, the PX 770 will look good in any home.

With the Casio PX 770, you can now have the sound of a 9-foot concert grand piano at your fingertips. This is all thanks to Casio's proprietary sound source "AiR" (Acoustic and intelligent Resonator). The sound source delivers the sounds with remarkable expression to ensure you always have a powerful performance.


Casio's AiR sound source

Thanks to Casio's Acoustic and intelligent Resonator (AiR) technology, you can experience the unprecedented tone of a grand piano. Now boasting an expanded memory module, the AiR can achieve longer samples than previous models. What does this mean for you? Longer samples decay more naturally without any looping or any other artificial effects.

When you play a grand piano, the sound you hear is not from one single note. Other strings with associated frequencies will resonate as well, adding their sound to provide a uniquely rich resonance.

Casio has digitally mastered this response to ensure every performance is expressively unique.

All 88 keys will continuously respond to the power behind each stroke. Every nuance of a pianissimo phrase, followed by the intensity of a fortississimo phrase will be replicated with exquisite detail. So whether you're reciting Debussy or Rachmaninoff, you can perform a truly organic experience.


Scaled hammer action

The Casio Digital Piano PX 770 features Casio's Tri-Sensor Scaled Hammer Action II keyboard. Thoughtfully designed to deliver the most natural and authentic playing experience, the PX 770 is meticulously engineered to recreate the weight, touch, and resistance of a grand piano.

The digital piano is made with simulated Ebony and Ivory textured keys, replicating the touch and playability of an acoustic grand piano. And thanks to the all-new tri-sensor system, you can accurately capture the tonal character of your performance with the PX 770.

Casio's PX 770 allows you to perform with total depth, character, and strength.


Stunning modern Piano design

The PX 770's design is ideal for the modern home environment. Despite having a full-size keyboard, the 770's cabinet is slim and easy to store in bedrooms and living spaces. There's an attached music rest that’s ideal for holding your books, smartphone, or tablet.

The sliding cover keeps the keys clean and dust-free when it is not in use.
