Tokyo, July 13, 2017 — Casio Computer Co., Ltd., announced today that it will release the Privia PX-870, a stylish compact digital piano that recreates the rich and expansive tone of a grand piano with the lid open.

The Privia PX-870 has a Sound Projection feature that uses punched metal slits in the top panel to enhance sound clarity. It also comes with a Lid Simulator function, a digital technology that was warmly welcomed with the earlier PX-860 model. This simulates the changes in a grand piano’s tone depending on the degree that its lid is open or closed. The combination of these two features allows the player to experience the rich and expansive sound of a grand piano played with the lid open.

The new digital piano also features the Casio Multi-dimensional Morphing AiR Sound Source,*1 which recreates the nuanced tonal variations and lingering reverberations of a grand piano. It uses digital technology to accomplish tonal changes based on both time passage and string resonance. In particular, the grand piano tone offers a more sophisticated timbre since temporal changes in the tone are controlled even more precisely.

  • *1 Multi-dimensional Morphing Acoustic & Intelligent Resonator (AiR) Sound Source

The PX-870 retains two popular features from its predecessor, the PX-860. Concert Play allows users to enjoy the feeling of performing at an orchestral concert by playing the piano together with the built-in recorded sound of a live orchestra. The keyboard is not only touch sensitive, but also offers precise control of attack timing.

The PX-870 is also the first Casio digital piano to offer Mobile Device Sync.*2 This allows Privia PX-870 users to practice using SMF data of their favorite songs loaded to a mobile app. They can even grade their practice using the app.

  • *2 Requires to-be-released free mobile app and commercially available adaptor and cable. See Main Specifications.

Casio will also be releasing other new digital piano products equipped with Mobile Device Sync: the Privia PX-770 with high-quality European grand piano tone and the CELVIANO AP-270 cabinet-style piano with a refined appearance and American grand piano tone.

Main Features

Sound Projection (available only with the PX-870)

The punched metal slits in the top panel of the compact 299mm deep body project a clear, distinct sound while maintaining the unique simplicity and beauty of the Privia’s appearance. The PX-870 also comes with the Lid Simulator function, a digital technology that simulates the changes in a grand piano’s tone depending on the degree that its lid is open or closed. Four effect levels corresponding to the degree the lid is opened can be selected to suit the user’s preference.

Sound quality calibration features, helpful for lessons (available only with the PX-870)

The PX-870 features Volume Sync Equalizer, which automatically adjusts sound to a pleasant tone quality in line with volume fader settings, and Headphone Mode, which optimizes sound expansiveness when the headphones are plugged in, allowing the player to practice at ease even at night.

Hall Simulator (available only with the PX-870)

The Hall Simulator allows the pianist to enjoy virtual experiences of the immersive sound properties found in four different types of venues, such as an Amsterdam church or a classical concert hall in Berlin.

String Resonance (available only with the PX-870)

String Resonance recreates more natural sounding reverberations of the piano by effectively reproducing the differences in the distinct string resonances of each of the keyboard’s 88 keys, as well as the differences that sound when a single note is played and when a chord is played, and the changes in resonance that correspond to the strength of the keystroke.

New grand piano tone suited to playing in a band (available only with the AP-270)

The new American grand piano tone (Grand Piano 2) gives players in pop or jazz situations to have a presence that won’t be buried by the other instruments in the group.

Classical music-oriented grand piano tone

The European grand piano tone, which has been popular with previous models, has even further evolved. Changes in sound waves are controlled based on time passage even more precisely than previous models to produce an even higher-quality sound.

Mobile Device Sync

Users can load their favorite songs in SMF data format into a new mobile app*3 and practice*4 them on the digital piano. Users can also separately practice the left and right hand parts while watching the musical score displayed on the mobile device screen. The new mobile app can also be used to grade practice results and manipulate digital piano settings.

  • *3 To be released on App Store and Google Play.
  • *4 Commercially available adapter or USB cable is necessary. Please see the Main Specifications for details.

Multi-dimensional Morphing AiR Sound Source

The Multi-dimensional Morphing AiR Sound Source reproduces the natural temporal changes in tone, as well as changes in volume and timbre depending on the force of the keystroke. It seamlessly reproduces the natural changes in tone from the moment a note sounds, through its beautiful sustain, until it finally vanishes away, including changes in both volume and timbre. Even the length of the reverberation can be controlled like an acoustic piano by adjusting the force of the keystroke. The player can also let beautiful resonating tones linger by using Damper Resonance, a function that reproduces the resonant effect of a damper pedal.

Tri-sensor Scaled Hammer Action Keyboard II

  • The Tri-sensor Scaled Hammer Action Keyboard II detects the force of keystrokes using three sensors per key to reproduce the distinct attack timing of acoustic pianos.
  • The Hammer Response reproduces the variations in the attack of the notes depending on how forcefully the notes are struck and the register of the keyboard.
  • The instrument’s black and white keys look and feel like real ebony and ivory for a luxurious feel and texture as well as a smooth touch.
  • The Key Off Simulator (available only with the PX-870) simulates the changes in tone according to how fast the finger leaves the key.

Concert Play

The spectacular sound of a live orchestra is recorded in a high-quality digital format. By playing the piano together with the recorded sound, users can enjoy the feeling of performing with an orchestra.
