The powerful tone of the acclaimed CFX concert grand piano
Newly sampled for the YDP-S54, the Yamaha's flagship 9' CFX concert grand piano, offers sparkling highs and a powerful resonant bass combined in a sound that projects to the furthest reaches of any concert hall. The CFX was played by the winner of the prestigious International Chopin Competition in 2010, and has since gained recognition as one of the greatest concert grands of modern times.
Authentic acoustic piano playability
With an 88-key piano action and synthetic ivory and ebony keys, the Graded Hammer 3 (GH3) keyboard reproduces the touch of an acoustic piano, from the heavy feel in the lower register to a lighter touch in the upper octaves. The GH3 features a three-sensor configuration that, accurately senses and interprets the behavior of the keyboard to provide a grand piano-style response and feel, allowing rapid note repetition and authentic expressive control.
Designed for your personal enjoyment
The YDP-S54 offers convenient functions for when you cannot always play the piano at high volume. Intelligent Acoustic Control (IAC) adjusts the sound automatically to allow players to enjoy balanced sound at any volume level.
Stereophonic Optimizer lets players enjoy the natural, spacious sound experienced when sitting in front of an acoustic piano, even when wearing headphones. When using this function, voices sampled from acoustic pianos are perceived to come from the body of the instrument itself, not your headphones, providing a comfortable, natural experience.
