Yamaha CSP255 Black

A Clavinova CSP designed to learn quickly, play better, and enjoy yourself

The Clavinova CSP-255 is part of the CSP-200 series, designed to bring the acoustic piano experience closer while offering a modern approach to learning. Its concept is based on a "frictionless" use: you choose a piece, the app displays the sheet music, and the instrument guides you note by note thanks to the Light Guide. The result: easier progress, maintained focus on playing, and keeping the joy of playing at the heart of the experience.

Keyboard Design

The GrandTouch-S 88-key keyboard aims to provide sensations close to a grand piano: mechanical with escapement, synthetic ivory and ebony key surfaces for better grip, and a response designed to work on dynamics. The touch sensitivity is adjustable (Soft2, Soft1, Medium, Hard1, Hard2, Fixed) to adapt the instrument to your technique, repertoire, and playing comfort. On the control side, the CSP-255 features 3 pedals (Damper with half-pedal function, Sostenuto, Soft), with assignable functions as needed.

Sound Quality

The sound base relies on the Yamaha CFX and Bösendorfer Imperial pianos, complemented by advanced expressiveness technologies: Virtual Resonance Modeling (VRM) to simulate the complex resonances of a piano, and Grand Expression Modeling to more finely translate playing intentions (attack, speed, intensity) into timbre variations. With a maximum polyphony of 256 notes and a 2 x 40 W amplification system powering 2 speakers of 16 cm, the CSP-255 offers a solid sound presence, suitable both for daily practice and enjoying an inspiring sound at home.
