Yamaha YDP-S55 B Digital Piano — Concert Grand Sound in a Slim Cabinet

The Yamaha YDP-S55 B is a slim 88-key ARIUS console digital piano finished in matte black, with a piano Voice meticulously sampled from Yamaha's flagship CFX concert grand. This model is the right choice for pianists who want authentic grand-piano tone and weighted touch without the footprint of an acoustic instrument.

What Sets the Instrument Apart in the ARIUS Line

Two technologies lift this piano above entry-level ARIUS models. Virtual Resonance Modeling Lite (VRM Lite) recreates the sympathetic resonance of an acoustic grand by simulating how strings and soundboard vibrate together, while the GH3 keyboard uses synthetic ebony and ivory keytops that absorb moisture and provide a grippy surface.

Keyboard and Touch — Authentic Acoustic Feel

The 88-key GH3 action is heavier in the bass register and lighter in the treble, mirroring the mechanical behavior of a real grand piano. Players benefit from rapid note repetition and expressive dynamic control, while the half-damper function replicates nuanced sustain control.

• 88 weighted keys provide a full concert range for classical repertoire and graded learning pieces.
• Keyboard Technology: Graded Hammer 3 (GH3) — weighted action with synthetic ebony and ivory keytops
• Touch Response: Hard / Medium / Soft / Fixed — adapts to beginners and advanced players alike
• Pedals: 3 (Damper with half-pedal, Sostenuto, Soft) — full acoustic-style sustain control

Sound Engine and Polyphony — CFX Grand With Room to Breathe

A 192-note polyphony ceiling keeps dense passages, layered voices, and long pedal sustains clean without dropped notes. Key-off Samples and Smooth Release add the subtle tonal shifts heard when fingers leave real keys at different speeds.

• Piano Sound: Yamaha CFX — flagship concert grand sample
• Polyphony: 192 notes
• Voices: 10 — including electric piano, organ, vibraphone, and strings
• Built-in Songs: 353 — 50 classics plus 303 lesson pieces from Beyer, Burgmüller, Czerny, and Hanon

Cabinet, Speakers, and Connectivity — Designed for Real Homes

The slim cabinet measures 1,353 mm × 792 mm × 309 mm, fitting comfortably against walls or in apartment corners. A folding key cover closes flush to create a flat tabletop, and the 20 W x 2 stereo amplifier drives a pair of 12 cm speakers.

• Dimensions: 1,353 mm × 792 mm × 309 mm
• Weight: 40.0 kg — stable cabinet with realistic key vibration feedback
• Amplifier / Speakers: 20 W x 2 / 12 cm x 2 — room-filling stereo without external monitors
• Headphones: Standard stereo phone jack (×2) with Stereophonic Optimizer for natural spatial sound

Who This Instrument Is For

It is the right choice for intermediate players and serious beginners who want full 88-key weighted action in a slim, room-friendly cabinet. Students preparing graded exams, adults returning to the piano, and home musicians who need authentic CFX grand tone with quiet headphone practice find it ideal. Smart Pianist app compatibility, Duo mode for teacher-and-student sessions, and a built-in metronome with a 5–280 tempo range cover daily practice needs.

The ARIUS Line and the CFX Concert Grand

Yamaha's ARIUS series bridges portable keyboards and the flagship Clavinova line, offering console-style digital pianos with authentic grand-piano sound engines. The CFX concert grand, sampled for this instrument, is the model Yamaha has chosen to represent the brand at international piano competitions, prized for its clarity across the entire keyboard and powerful bass projection.
