Yamaha CSP255 Polished Black

A Clavinova Approach Designed to Play More, Learn Better

Within the Clavinova universe, the CSP-255 stands out with a philosophy centered on visual accompaniment and interaction with the Smart Pianist app. Where other digital pianos favor a classic interface, the CSP series emphasizes a smooth experience: sound selection, sheet music display, coaching and playing assistance, to progress without breaking the musical flow. The result: a furniture digital piano that is both inspiring for interpretation and highly effective for structuring daily practice.

Keyboard Design

The CSP-255 features a GrandTouch-S 88-key keyboard designed to provide familiar piano references: weighted touch, piano-oriented mechanics, synthetic ivory and ebony surfaces for better grip, and escapement for a more realistic response in subtle playing. The sensitivity is adjustable (Soft2, Soft1, Medium, Hard1, Hard2, Fixed) to adapt the response to your technique, from beginner to advanced pianist. On the control side, there are 3 pedals (damper with half-pedal, sostenuto, soft) with extended functions (sustain, glide, style start/stop, volume, etc.).

Sound Quality

The sound generation highlights two premium pianos: Yamaha CFX and Bösendorfer Imperial, enhanced by binaural sampling (CFX Grand and Bösendorfer only) for a more immersive headphone experience. The Virtual Resonance Modeling (VRM) technology reproduces complex resonances (strings, soundboard, sympathetic vibrations), while Grand Expression Modeling refines the translation of touch nuances into timbre variations. With a maximum polyphony of 256 notes, a large sound library (772 voices + 47 drum/SFX kits, totaling 819), and amplification of 2 x 40 W through 2 speakers of 16 cm, the CSP-255 delivers a wide, expressive, and stable sound, even in very dense passages.
