The YDP-S55 models all features a piano Voice sampled from Yamaha’s flagship CFX concert grand piano—a renowned piano that delivers sparkling highs and a powerful resonant bass combined in a superbly expressive sound. The YDP-S55 has the same detailed sound—from the lower keys to the higher keys—full of clarity and rich in colorful harmonic content. It gives you extraordinary expressive power and nuance, that authentically responds in your daily practice as well as your most emotion-filled performances.

With an 88-key piano action, the GH3 (Graded Hammer 3) keyboard reproduces the touch of an acoustic piano, from a naturally heavy feel in the lower key to a lighter touch in the upper octaves. The GH3 keyboard provides a grand piano-style response and feel, allowing rapid note repetition and authentic expressive control. Moreover, there’s a half-damper feature that authentically replicates the damper action on a grand piano, providing rich expressive variation.

One of the allures of the grand piano is the sympathetic resonance created by the vibration of the entire instrument. The YDP-S55 elaborately reproduces this rich sympathetic resonance through a groundbreaking technology called Virtual Resonance Modeling Lite (VRM Lite). VRM Lite creates a richly varied sound by simulating the complex sympathetic tones created when the vibrations of the strings are propagated to the soundboard and other strings, corresponding to the timing and intensity of key playing and pedaling.

Naturally, the YDP-S55 has an authentic grand piano sound, but it also features various other built-in instrument sounds, for a total of 10 Voices—including electric piano, organ, vibraphone, and strings. The YDP-S55 also has 353 built-in songs, including 50 famous classical songs, and 303 comprehensive practice exercises from famous methods, such as Beyer, Burgmüller, Czerny, and Hanon. The instrument is also compatible with Yamaha's free Smart Pianist app—simply download the app to your smart device and connect it to the instrument*. With the Smart Pianist app, you can easily operate the various Voice functions of the instrument and use it to call up scores of the built-in songs. It also features a comprehensive Piano Room function for changing the tonal quality and resonance settings of the piano sound. * A cable connection is required. Make sure to purchase the correct cable for your smart device.

The YDP-S55 employs new technology that corrects the sound balance optimally according to the volume you set—giving you an exceptionally natural sound that’s easy to listen to and is gentle on the ears, even when playing for a long time. It also has Stereophonic Optimizer effect that lets you enjoy the natural, spacious sound you experience sitting in front of an acoustic grand piano, even when wearing headphones.

The piano cabinet has a slim depth that lets you neatly install it in any room, and makes for a chic, stylish design that effortlessly enhances your living space. Moreover, closing the keyboard lid gives the instrument a flat, unassuming look.
