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.

Utilizing the same hammering system and spring-less mechanism as a grand piano, GH3 keyboard action reproduces the touch of an acoustic piano from the heavy feel in the lower register to the lighter touch in the upper octaves. It also features the three-sensor configuration, which accurately senses and interprets the behavior of the keyboard for a response and feel very similar to that of a grand piano.

Reproduces the gentle, tactile surface of the ivory keyboards once used in only the finest pianos. It features highly-absorbent material that prevents fingers from slipping even after hours of performing, while retaining the ideal texture and feel.

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. Subtle changes occur when the player begins to press the pedal while striking a key.

The Yamaha digital piano is pre-loaded with a variety of classic piano songs for your 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 simply listen to the songs and enjoy these recognizable piano favorites. This feature is sure to add hours of enjoyment to this terrific instrument.

The recording function built into the instrument allows players to record performances* with a single touch. Additionally, players can record up to 2 tracks for simultaneous playback, meaning that both hands can be recorded separately.* Recordings are made in Standard MIDI file (SMF) format. Compatible software is required for playback of the recorded data on a computer.

The "Digital Piano Controller" app has an attractive interface optimized for iOS touch screens, adding a whole new level of functionality to your Yamaha instrument. Turn your iOS device into an intuitive instrument controller, allowing you to access features and settings even more quickly than using the panel of your instrument. Adjust settings, choose Voices, and even record performances. Once you try it, you'll never want to live without it!

Combine two Voices together, like piano and strings, for an inspiring new playing experience. Nothing livens up piano practice like playing a piece with a different sound, and creating unique combinations of two sounds together. Experiment with these combinations to discover new inspiration.

With the Yamaha exclusive Intelligent Acoustic Control (IAC) feature, people can enjoy playing their digital pianos at a lower volume in a quiet home environment. Before IAC was introduced, playing at a low volume resulted in a loss of treble and bass. With the addition of IAC, the instrument automatically adjusts the balance of bass and treble, creating a truer sound with more depth. Additionally, the volume dial automatically makes fine adjustments to the overall sound of the speaker system (EQ) when played at a low volume. This ability to retain a rich and balanced sound on the digital piano, regardless of volume, ensures the highest sound quality.

Yamaha developed this new technology with an in-depth knowledge of the acoustic properties of musical instruments. Acoustic Optimizer delivers naturally smooth tonal richness across the entire keyboard by regulating the flow of sound and control of tone from the cabinet of the instrument.

The Stereophonic Optimizer is unique to Yamaha. When playing and listening to the instrument using headphones, the Stereophonic Optimizer adjusts the spacing of the sound and the separation from the piano, resulting in a spacious, surround sound quality that will inspire you to play for hours at a time. Within this private listening environment, the sound of the piano can be perceived to come from the body of the instrument rather than from the headphones, providing a more realistic and natural experience.
