SuperNATURAL Piano sound engine
The HP307 is equipped with our 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 Roland's deep research of the characteristics of acoustic pianos, with the goal of faithfully reproducing the rich tone and expressivity of a concert grand piano. The maximum polyphony of 128 is more than enough for even the most complex pieces.
Expressivity in every single key
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 colour 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.
Expressivity according to the player’s touch
Pianos produce differences not only in volume, but also subtle variations in tone colour, 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 colour 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.
Expressivity of decaying sounds
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 colour to a softer tone. The SuperNATURAL piano sound engine replicates this natural decay, just as in an acoustic grand.
True Touch into True Sound with PHA III
Inherited from Roland’s flagship V-Piano, the HP307's PHA III Keyboard with Escapement offers maximum comfort, playability, and response. PHA III improves key repetition. The combination of PHA III and SuperNATURAL piano faithfully translates the most subtle performance nuances into natural, accurate sound. The keyboard expresses the player's articulation perfectly from delicate to full-impact, as well as each independent note in rapid succession ― including sustained tones. The escapement mechanism recreates the authentic "click feel" of a grand-piano keyboard, which particularly enhances expression when playing pianissimo. The keyboard also features Roland’s acclaimed Ivory Feel ― a comfortable and realistic moisture-absorbent material that prevents slipping from perspiration during performance.
