Casio Releases New Privia Stylish Digital Pianos with Rich Grand Piano Sound, Seamlessly Smooth from Pianissimo to Fortissimo New Sound Source and Keyboard Technologies Enhance Expressiveness of Digital Piano

PX-730BK

TOKYO, July 22, 2009 — Casio Computer Co., Ltd., announced today the release of three new models in its distinctively stylish series of Privia digital pianos. The PX-730, PX-330 and PX-130 use new sound source and keyboard technologies to naturally express the full spectrum of rich grand piano tones from pianissimo to fortissimo. The new pianos all capture the essence of the Privia brand: a stylish, compact, lightweight musical instrument that makes it easy to enjoy playing the piano and can match the décor of almost any room in the home. They also boast improved essential piano components of sound and keyboard in an effort to reproduce all the qualities of a grand piano. The new additions include the PX-730, which features an integrated stand and pedals, ideal for piano performances; the PX-330, a multi-function model that can be used as a stage piano; and the PX-130, a compact unit with a simple, modern design. Newly developed Linear Morphing AIF Sound Source The tone of a musical note changes depending on the amount of force used to strike the key. In the past, the difference in force was reflected in the piano sound by filter processing three sounds (weak, moderate, strong) for each note sampled from a concert grand piano. However, when the strength of the notes changed from weak to moderate or moderate to strong, there was an abrupt change in sound which limited the digital piano’s effectiveness in reproducing a grand piano’s natural tone transition from weak to strong notes. The newly developed Linear Morphing AIF Sound Source does not rely on filter processing to change the tone depending on the force applied to the key. Instead, Casio uses an original algorithm to create each sound individually across the note spectrum, which has successfully enabled these three new pianos to reproduce fully natural sounds. With this new technology, these pianos feature completely smooth changes in tone, just like an acoustic piano. Further, the new sound source’s dynamic range enables rich sound reproduction from very softly played notes to very forcefully played notes. Tri-sensor Scaled Hammer Action Keyboard The number of sensors which detect key strokes has been increased from two to three in the newly developed Tri-sensor Scaled Hammer Action Keyboard. When a key is not fully released and then pressed again, the new pianos will continue to play the same note, recreating the action of a grand piano. There are no springs in the keyboard — the keys move completely under their own hammer weight. Lower notes play relatively heavier than higher notes, with a realistic key touch.
