Yamaha YDP-S55 White Digitalpiano

Yamaha YDP-S55 WH — Slim Console Piano with CFX Grand Sound

The Yamaha YDP-S55 WH is a slim 88-key console digital piano built for living rooms and apartments where floor space is limited. Its matte white cabinet folds flat into a tabletop when closed. Inside, the GH3 keyboard with synthetic ebony and ivory keytops replicates acoustic grand touch, while the Yamaha CFX concert grand Voice anchors the sound. This model suits pianists who want authentic grand feel without the footprint of a full upright.

What Sets the YDP-S55 Apart

The YDP-S55 includes Virtual Resonance Modeling Lite (VRM Lite), which recreates the sympathetic string vibrations of a real grand piano. Smooth Release samples the subtle change when keys are released slowly. The half-damper feature on the sustain pedal replicates the expressive control of acoustic grands.

Weighted Keyboard Action — Authentic Grand Touch

The GH3 mechanism grades the weight from heavier lower keys to lighter upper octaves, matching acoustic grand feel. Synthetic ebony and ivory keytops absorb moisture and provide grip during long sessions.

• Keyboard Technology: Graded Hammer 3 (GH3) — graded hammer action with synthetic ebony and ivory keytops
• Keys Number: 88 — full concert range for classical repertoire
• Three-pedal complement — Damper with half-pedal function, Sostenuto, and Soft replicate the acoustic grand pedal layout

Tone Generation and Polyphony — CFX Grand Sound

The piano Voice is sampled from Yamaha's flagship CFX concert grand, capturing sparkling highs and a powerful resonant bass. VRM Lite and 192-note polyphony keep complex pedaled passages free of dropped notes.

• Piano Sound: Yamaha CFX Sampling — flagship concert grand Voice
• Polyphony: 192 notes — headroom for layered performances with pedal
• Ten built-in Voices — including electric piano, organ, vibraphone, and strings for tonal variety beyond the acoustic piano

Cabinet, Speakers, and Connectivity

The slim cabinet houses a built-in stereo speaker system, dual headphone jacks for silent practice, and USB TO HOST for MIDI connectivity. The Smart Pianist app adds score viewing and voice control.

• Speaker Built-in: Yes (12 cm x 2, 20 W x 2 amplifier) — fills a small-to-medium room
• Headphone Output Port: Yes (Standard stereo phone jack x 2) — two-person silent practice
• Slim cabinet footprint — 1,353 x 792 x 309 mm fits tight living spaces while the folding lid creates a flat tabletop when closed

Ideal Player and Use Cases

The YDP-S55 is the right choice for intermediate students, returning adult pianists, and apartment dwellers who need authentic weighted feel in a slim cabinet. CFX sound and half-damper control support classical repertoire practice, while 353 built-in songs (50 classics plus 303 lesson exercises) make it a self-contained practice station. Without arranger or guided learning features, the interface stays clean for focused practice.

The ARIUS Line — Yamaha's Accessible Console Piano

Yamaha's ARIUS series launched roughly a decade ago as a more affordable alternative to the Clavinova line, originally featuring a slim cabinet that doubled as a desk surface. Over the years, the line absorbed trickle-down technology from Clavinova, including the GH3 action and CFX sampling. The YDP-S55 continues that philosophy in a slim cabinet.
