Casio Privia Product Details

Unprecedented Natural Reproduction of the Rich Expressive Power and Resonance of an Acoustic Piano – The Casio Privia Range

Simulating the Delightfully Delicate Reverberation and Rounded Resonance Associated with Pianos

Multi-dimensional Morphing AiR Sound Source

More natural waveform data sampling with a higher capacity memory

The acoustic level achieved by a digital piano is determined by the capacity of the memory that stores sounds after sampling. A new high-capacity memory, boasting a capacity in excess of approximately three times our previous models (converted linearly), is installed for the Multi-dimensional Morphing AiR sound source. The waveform data sampling capacity has increased dramatically, enabling natural reproduction of the delicate changes in waveforms associated with concert grand pianos. The sound quality and resonance have achieved astonishing evolution, realizing an ability to produce simultaneous sounds comprising up to 256 notes in high-end models ( PX-5S, PX-850).

Reproduced sound quality closely approaching the original sound [Lossless Audio Compression]

Digital pianos normally compress and record sound waveform data in their built-in memory. This data is then expanded and played back when recalled. As in the case of compressed audio data such as MP3, therefore, the played-back sound simply cannot avoid deterioration with respect to the original sound. But the advanced Lossless Audio Compression technology adopted for CASIO’s Multi-dimensional Morphing AiR sound source has made it possible to reproduce sounds without this deterioration of the original sound quality. This permits enjoyment of musical performances with acoustics that are immeasurably closer to natural piano sounds.

88-key stereo resonance simulator reproducing a deep acoustic piano resonance

String Resonance* resonator achieving deep, rich resonance with 88 keys

The sound produced by an acoustic piano is not only the sound associated with the keys that are struck. Other strings with frequencies closely associated with those producing the sounds resonate as well, adding their sound to give the music a uniquely rich resonance. In ordinary digital pianos, this string resonance effect is reproduced virtually with strings. The Multi-dimensional Morphing AiR sound source takes a different approach, however, by adopting a “string resonance” system incorporating a stereo resonance simulator for all 88 keys. The resonance of the 88 keys is reproduced completely and naturally. The resonance realized by playing a single tone is differentiated from that realized by playing a chord to reproduce the resulting variations in resonance in a natural manner. This even enables players to achieve varying resonances, controlling them at will by the strength of their touch, and thus to realize performances with the unique expressiveness of an acoustic piano. * PX-850 only

Damper Resonance*1 achieving a more naturally beautiful resonance than a pedal

The deep, beautiful resonance resulting from the use of a damper pedal is also reproduced naturally by a stereo resonance simulator installed on all 88 keys, an approach that differs from conventional simulated reproduction employing effect processing. The attention to detail goes so far as to simulate the resonance created by the lifting of the dampers themselves when the pedal is pressed. 　 A continuously variable system*2 has been adopted for the damper pedal, moreover, reproducing even the subtle changes in reverberation that occur in response to the delicate pressure exerted by partial pedal operation. This enables players to employ pedal operation to achieve gracefully expressive performances.

*1 PX-850 models offer 4 adjustment levels. *2 PX-850 only

Equalizing technology pursuing the acoustic balance of a grand piano

With an acoustic piano, the strings’ vibrations are amplified by the soundboard, generating sound from throughout the instrument. CASIO’s new equalizing system imparts a unique sensation of three-dimensional depth and creates a natural sound space. It represents yet another advance in the pursuit of optimal sound and playing pleasure.

Lid Simulator* reproducing the sound effects resulting from an open lid

The sound volume and quality change when the lid on a grand piano is raised or lowered. The Lid Simulator reproduces the same acoustic effects for enhanced enjoyment with a digital piano. The acoustic effects of opening and closing the lid are simulated in fine detail. The piano sound you are seeking as you play is always available for your enjoyment by selecting the degree to which the lid is raised or lowered. * PX-850 only * The Lid Simulator setting value remains unchanged, regardless of whether the lid on the piano body is open or closed.

Keyboard System

Natural Playing Feel Approaching That of a Grand Piano

Firm Touch That Converts the Player’s Thoughts into Sound Tri-sensor Scaled Hammer Action Keyboard II, with a grand piano’s unique sounding timing The difference between the sound structures of a grand piano and a digital piano appears as a difference in timing, from the moment the instrument is played until the sound is audible. The new Tri-sensor Scaled Hammer Action Keyboard II responds by incorporating a system with three sensors that detect touches of the keys sequentially. This permits minute variations in the time between detection of a keystroke and sound production, depending on the speed of the keystroke. The sensor system also enables a sound to be produced continuously, even when the key has not fully returned to its resting position, a feature assuring excellent playability when the same note is struck repeatedly. Also as in a grand piano, moreover, the action mechanism relies solely on the weight of the hammer, with absolutely no springs employed, thus providing both a definite playing response and a smooth touch. The keys become progressively heavier as the sound becomes lower and progressively lighter as the sound becomes higher, faithfully simulating this characteristic of an acoustic piano.

Hammer Response reproducing even differences in sounding timing among key blocks

The sizes of the hammers that strike the strings differ among the various key blocks in a grand piano. The sounding timing consequently varies subtly, even when keys are struck with the same strength. The new keyboard system carefully reproduces these differences in sound production timing from one register to another. It even simulates the differences in sound production timing according to the force with which a key is struck.

Key Off Simulator* reproducing tonal variations resulting from finger release

The lengths of the reverberations and expressions a piano produces vary depending on the speed at which players release their fingers after touching the keys. The new keyboard system incorporates a Key Off Simulator that reproduces these nuances resulting from key release naturally. Authentic reverberations that feel just like those of a grand piano are expressed as a result.

* * PX-850 only

Simulated ebony and ivory keys with optimal fingertip fit for playing ease

The Simulated ebony and ivory keys offers the luxurious feel and texture as well as the smooth touch of a grand piano keyboard. This is a standard for all the Casio Privia Digital Piano Models. The minutely detailed crimp surface finish inhibits finger slippage due to sweat and gives the sensation of a perfect fingertip fit, even when playing for extended periods.

Privia pursuing smart functional beauty

The lightweight, compact body has been refined further to enhance Privia’s functional beauty. The original external styling presents a sharp, slim-lined image possible only with electronic instruments. Other attractive features include a selection of colors to match any home interior. The lineup even includes keyboard-style models that can be played on a tabletop or transported to another venue for virtually unlimited playing freedom.

Use of AUDIO RECORDING* to record performances and teach lessons

The sound of a piano performance can be recorded in digital format on USB flash drive using a port on the piano body. This not only permits playback of recorded performances, but the recordings can also be used to accompany a pianist during performances. The digital sound data can also be played back on a PC using standard audio file playback software. * PX-850, PX-780M, PX-350M

Identical tonal ranges can be set to the right and left of center on the keyboard. This Duet Mode is convenient when two players, such as a parent and child or a teacher and student, are practicing together. PX-850, PX-750, PX-150 models are equipped with two GRAND PIANO mode buttons and an ELEC PIANO mode button that are selectable in a single operation, depending on the music to be played or the pianist’s personal preference.

The Casio Privia PX-780M, PX-350M feature a Tone Select button that makes it easy to choose a tone from the abundant available selection. The Metronome Function and Recording Function come in handy when practicing the piano. The Music Library is both an excellent listening resource and a useful tool for lessons. (Musical score collection bundled* with models except PX-350M). * Some musical scores may not be included due to copyright issues.

The Layer Function enables players to overlap two types of tones, while the Split Function can be used to separate tones into lower and higher blocks.

The Panel Lock feature is designed to prevent unintentional setting changes by locking the button operations.

Auto Power Off is a practical feature that prevents wasteful electric power consumption by shutting off the power automatically when no operation has been conducted for a certain period of time.
