Piano sound quality only possible from Yamaha
The Pure CF Sound Engine is the result of many years of piano-making history and expertise, combined with state-of-the-art sampling technology. Yamaha is the industry leader in digital piano technology, and this is evident when listening to Yamaha digital pianos that utilize the Pure CF Sound Engine. The sound of the renowned Yamaha CFIIIS 9′ concert grand piano is faithfully reproduced, allowing for incredible dynamics and expressiveness, making Pure CF-equipped digital pianos worthy of the Yamaha name.
Superb playability and feel
Graded Hammer 3 (GH3) 88-key piano action reproduces the touch of an acoustic piano, from the heavy feel in the lower register to a lighter touch in the upper octaves. It also features a three-sensor configuration, which accurately senses and interprets the behavior of the keyboard in order to provide a grand piano-style response and feel. This allows for quick note repetition and authentic expressive control. The piano keyboard with synthetic ivory key tops provide a tactile surface to the white keys, absorbing moisture from the fingers and preventing them from slipping.
Pedaling provides an added level of realism
Half-damper pedal control creates more detailed nuance and subtlety when playing, similar to pedaling on a grand piano. This feature allows for continuously increasing lengths of sustained notes, from slight to full, as the sustain pedal is depressed. Stereo Sustain samples provide mellow reverberations when the player depresses the damper pedal. Similarly, Damper Resonance provides broad and deep resonance when the pedal is used. The result is more realistic sound, similar to that of an acoustic piano. It is possible to detect the subtle changes that occur when the players begins to press the pedal while striking a key.
A piano with its own classic repertoire
The Yamaha digital piano is pre-loaded with a variety of classic piano songs for listening and learning pleasure. Players can use the accompanying book, “50 Greats for the Piano” to follow along with the music and learn how to play iconic pieces. They can also play back the songs to enjoy these recognizable piano favorites. This feature is sure to add hours of enjoyment to this terrific instrument.
