Designed for beginner to advanced pianists, the YDP-S55 features an improved sound engine to the Yamaha CFX concert grand piano, and the touch of the revered Graded Hammer 3 (GH3) keyboard with synthetic ebony and ivory key tops. The YDP-S55 features a slim design, making it an ideal choice for those with space constraints, such as college students or people living in smaller apartments.

Connecting to the Smart Pianist app for iOS adds a graphic user interface that makes selecting Voices or configuring settings even easier. Smart Pianist can even analyze songs stored in your music library and display a chord chart, allowing you to learn and play along with your favorite songs.

Features:

- CFX Stereo Sampling faithfully reproduces the sound of Yamaha's flagship CFX Full Concert Grand.

- Graded Hammer 3 (GH3) with synthetic ebony and ivory key tops add a tactile surface to the keys, which absorbs finger moisture and prevents slipping.

- VRM (Virtual Resonance Modeling) Lite technology makes the sound more like that of a real acoustic piano by reproducing the sophisticated string resonance of an acoustic piano.

- Intelligent Acoustic Control (IAC) automatically adjusts the EQ of the built-in stereo speaker system to the player's setting, ensuring the richest tone at any volume level.

- Stereophonic Optimizer adjusts the spatial distribution of sound in the listener's headphones, creating the sensation that sound is coming directly from the piano, rather than from the headphones.
