| TOKYO, July 22, 2009— Casio Computer Co., Ltd., announced today the release of three new CELVIANO digital pianos. The AP-620, AP-420 and AP-220 express the full spectrum of rich tones from pianissimo to fortissimo, just like a grand piano. |

Casio’s CELVIANO pianos are designed to maintain the elegant appearance of a piano. As authentic cabinet-type pianos, they are ideal for lessons. The new models feature sound source and keyboard technologies that place them a full generation ahead of other digital pianos currently on the market. These advances make the CELVIANO experience virtually the same as the rich, natural sound quality and feel of a grand piano.
Three new models are joining the CELVIANO series; the top-of-the-line AP-620 boasts a refined design and numerous extra features; the standard model AP-420 offers balanced functionality that makes it ideal for most music students; and the basic model AP-220 offers all the essential functions that make piano playing enjoyable. |

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. The newly developed Linear Morphing AIF Sound Source does not rely on conventional 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.
| * 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. |
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. |
