لوحة مفاتيح بيانو GP-510BP Celviano Grand Hybrid 88-Key من كاسيو

On an acoustic grand piano, the volume and quality of sounds change from the time the keys are struck until they die away. Casio’s Multi-dimensional Morphing technology enables natural, smooth transitions in sound volume and tone based on the power of the keystroke. This technology contributes to more expressive performances.

The various types of resonance in a grand piano are crucial to the playing experience. The CELVIANO Grand Hybrid incorporates String Resonance, which exposes the harmonic relationships between various strings when keys are struck. Also Damper Resonance reproduces the resonance occurring when a damper pedal is pressed. The GP-510BP is equipped with Open String Resonance and Aliquot Resonance functions for enhanced realism. Casio’s Resonance System reproduces the resonance of both the strings and sound board of a grand piano by selecting, controlling and synthesizing according to performance conditions.

A grand piano also generates several types of mechanical sounds, which are an important part of the playing experience. Casio has sought to provide a more realistic simulation by reproducing the sounds of these mechanisms. Four types of operating sounds are included, and the volume of each can be set independently or turned off.

The CELVIANO Grand Hybrid incorporates AiR Grand Sound Source, a system using Casio’s state-of-the-art sound technologies. It includes many impressive features. Multi-dimensional Morphing delivers smooth changes between soft and strong playing. Acoustic Simulator reproduces the characteristics of sounds produced by acoustic grand pianos. The authenticity generated by the AiR Grand Sound Source ensures a pure piano experience.

The lengths of the lingering sounds produced by a grand piano vary depending on the speed at which players release their fingers after pressing the keys. In a similar fashion, Casio’s Key Off Simulator controls the length of these sounds based on the key’s release speed and delivers a natural decay of the sound. This enables players to express delicate nuances when playing staccato and legato.

The timing of a grand piano’s sound varies subtly depending on which keys are being played, even when the keys are struck with the same force. To achieve optimal authenticity, Casio has installed appropriate settings for each of the three grand piano tones. The sound production timing can also be adjusted to suit the player.

By continuously sensing and detecting the position of the damper pedal, Casio’s Grand Pedal System enables fine-tuning of the damping volume and note length depending on the degree of pedal depression. In addition, the Half Pedal Position function permits adjustment of the depression position at which the damping effect comes into play according to the player’s preference. For performances which utilize the soft pedal, the change in volume and characteristics of sound is extremely natural where the player can enjoy a wide range of expression when playing softly. The Action Sound System’s Damper Noise and Pedal Action Noise features reproduce even subtle operating sounds like those experienced with an acoustic grand piano.

Casio has developed a new dedicated speaker system for the CELVIANO Grand Hybrid that reproduces the characteristics of sound emanating upwards and downwards from an acoustic grand piano. This enables powerful and dynamic expression from rich, stately bass to bright mid-high sounds. The four-channel audio system incorporates six speakers, carefully positioned in a structural design that releases sound outward from the interior of the body. The system delivers the same sound field experience a player would enjoy while playing an acoustic grand piano.
