The RD-700GX SuperNATURAL Piano Kit is designed to add three dimensions of seamless piano perfection to your RD-700GX. The kit provides Roland's newly developed SuperNATURAL Piano sound engine, which was born by bringing together V-Piano technology and 88-key stereo multisampling technology. This new sound engine is the product of our deep research of the characteristics of acoustic pianos, with the goal of faithfully reproducing the rich tone and expressivity of a concert grand piano.

Each of the 88 notes on a grand piano has its own character, due to the fact that the strings are different sizes and lengths, use different materials, and are struck by hammers of different sizes. These differences create variations in the tone color and resonance of each note. For the new SuperNATURAL Piano sound engine, Roland sampled all 88 notes of a variety of world-class pianos and used its unique digital technology to faithfully reproduce the full, rich tone and expressivity of the world's finest pianos.

Pianos produce differences not only in volume, but also subtle variations in tone color, depending on how forcefully the key is struck. Using Roland's latest technology, the SuperNATURAL Piano sound engine delivers natural and seamless changes in tone color in response to the player's touch. Its expanded dynamic range supports the most advanced and subtle techniques, just as one would expect in an acoustic grand piano.

The natural decay of notes and beautiful lingering tones are important elements of a piano's sound. The decaying sound of an acoustic piano not only decreases in volume, but also gradually changes in color to a softer tone. The SuperNATURAL Piano sound engine replicates this natural decay, just as in an acoustic grand.
