Grand PianoThe RD-700NX’s acoustic piano sounds are derived from Roland’s acclaimed SuperNATURAL Piano sound engine. There are three acoustic piano types onboard (Concert, Studio, and Brilliant) and 30 variations to choose from. With SuperNATURAL Piano technology, three essential elements are dramatically improved: velocity response, note decay, and key-range behavior. Where previous technology created coarse “stair-step” gaps in velocity and key range, and unnatural looping in note decay, SuperNATURAL Piano bridges the gaps with perfectly smooth and natural three-dimensional sound and response.E. PianoFor EP lovers, the RD-700NX contains a SuperNATURAL-based electric piano that meticulously models vintage electric pianos from the 1960s, ’70s, and ’80s. Beyond standard EP modeling, SuperNATURAL technology enables completely new types of EP sounds to be created. You can change the position of the virtual pickups, for example, or exchange components of the sound generating system entirely.PHA III KeyboardThe RD-700NX’s PHA III Keyboard with Escapement offers maximum comfort, playability, and response. PHA III improves key repetition and perfectly conveys dynamic, velocity-based tonal changes. 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. The authentic coloration of grand-piano keys can also been seen on the sides of the white keys.Sound FocusThe innovative Sound Focus feature ensures that every note will be heard, even subtle pianissimo passages. Based on SuperNATURAL phase-correction technology, this essential feature ensures the RD-700NX won’t get lost in the mix, penetrating through walls of sound without compressing or coloring the tone. Players can relax and play naturally, achieving presence onstage without sacrificing dynamics and sound quality.One-Touch AccessThe popular One Touch Piano feature from previous RD-series pianos has been enhanced in the RD-700NX. It provides instant access to standard piano sounds and setups with the touch of a button. Three types of acoustic pianos and three types of electric pianos are now available for instant One Touch recall.Sight & SoundAlong with the gorgeous grand pianos and EPs, hundreds of additional sounds are built into the RD-700NX: 242 tones, 10 Tone Wheel organs, 256 GM2 tones, 5 rhythm sets, and 9 GM2 rhythm sets in all. Sifting through the sound library is fast and convenient with the new, high-resolution LCD, which provides clearer visibility and a beautiful graphical user interface.
