    Casio PX-850 Privia Digital Piano Product Description

    The flagship of Casio's Privia line, the PX-850's advanced AiR sound set provides an additional level of realism, including grand piano lid simulation and sympathetic resonance. The PX-850 has a dual 20-watt speaker system and a cabinet that opens providing a rich concert sound.

    The Flagship

    The PX-850 represents a significant step in the continuing evolution of the Privia digital piano line. A combination of a keyboard action and a powerful sound engine provide a high level of detail, nuance and expression for a superior grand piano experience in the lightweight and stylish design that Privia is known for. The PX-850 has 18 Instrument tones (5 are Piano), and 256 note polyphony. The PX-850 keys feature Damper Resonance, Hammer response and Sympathetic Resonance. Another feature to enhance the realistic feel of a grand piano is the lid simulation. You can choose (separate from what the actual PX-850 cabinet will do) whether you want the lid on the Grand Piano open, closed, half or removed. The PX-350 has 1/4" audio outputs and USB-to-Device output so you can easily connect the PX-850 to recording and sound reinforcement equipment.

    Multi-Dimensional Morphing AiR Sound Source

    The characteristics of Casio's Multi-dimensional Morphing AiR (Acoustic and Intelligent Resonator) Sound Source reflect thorough attention to detail in expressing the rich, resonating tones inherent to the piano. The capacity of the installed memory has been expanded to achieve a longer sampling duration and enhanced waveform data quality. The temporal changes in tone that create sound you would expect only from a piano, beginning with the initial sound and leading into a beautiful extension until the sound eventually vanishes, are reproduced naturally.

    Keyboard System

    Natural playing feel approaching that of a grand piano firm touch that converts the player's thoughts into sound. 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 Tri-sensor Scaled Hammer Action Keyboard II responds by incorporating a system with three sensors that detect touches of the keys sequentially.

    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. 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.

    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. The Lid Simulator setting value remains unchanged, regardless of whether the lid on the piano body is open or closed.

    An Unprecedented Evolution of the Digital Piano

    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.

    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 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.

    Damper Resonance. Achieving a more naturally beautiful resonanceThe 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 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.
