SuperNATURAL Piano


Flagship Model That Offers the Ultimate in Piano Tone and Expressivity

The look and sound are pure, natural, and timeless, but inside the wood cabinetry is the most advanced technology on the home-piano market. The new HP-307 takes a giant leap forward with the advent of Roland’s SuperNATURAL Piano sound engine, a breakthrough technology that offers unprecedented sound, response, and feel. The piano tone changes seamlessly and naturally based on touch and key range, with perfectly smooth decay. The HP-307 is equipped with a PHA III keyboard, which delivers enhanced expression and superior rapid keystroke performance. The combination of PHA III and SuperNATURAL Piano faithfully translates every nuance into accurate, natural sound. The HP-307 is available in three colors: an elegant polished ebony finish, traditional rosewood finish, or cool satin black finish. The innovative Individual Twin Piano feature allows side-by-side practice or performance. The 3-track recorder enables you to record your performance and will also be a great help when practicing right or left hand parts individually.

SuperNATURAL Piano

The HP-307 is based on Roland’s new SuperNATURAL Piano engine — a breakthrough technology derived from the flagship V-Piano, as well as 88-key stereo multisampling. SuperNATURAL Piano brings a new level of authentic sound and natural performance to the digital domain. Roland’s engineers relentlessly analyzed the complex, ever-changing characteristics of concert grand pianos, faithfully capturing and reproducing the tonal variations based on the velocity of each keystroke. Three key elements have been dramatically enhanced: velocity response, note decay and key-range behavior. The end result is an incredibly expressive and authentic sound that blurs the line between digital and acoustic.

True Touch into True Sound with PHA III

Inherited from Roland’s flagship V-Piano, the HP-307’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.

Classic Cabinetry

The HP-307 is available in gorgeous wood cabinets with a traditional rosewood finish, cool satin black finish, or the beautiful, luxurious Polished Ebony finish. The HP-307 offers a Classic Position key lid that can be positioned to conceal the control panel, as well as elegant and solid front legs, classically shaped triple pedals and a convenient music score holder on music stopper.

“Piano Designer” Sound Customization

For those who wish to customize the piano sound to suit their personal taste, the Piano Designer feature allows friendly access to a variety of tone-shaping controls. Fine adjustments, with visual confirmation from Graphic LCD display, enable you to get the sound qualities you want, such as Cabinet Resonance or the effects of different positioning of the “virtual” grand piano lid. Create the perfect custom sound, and save it for instant recall.

Two Pianos in One!

For side-by-side practice or performance, you can divide the keyboard into left and right zones with Twin Piano mode, which allows two people to play the same range of pitches. It’s like having two independent pianos spread across one keyboard. You can choose to have the two zones blended or separated (Individual mode) so sound of the right-hand keyboard zone is heard only from the right speaker and the sound of the left-hand zone is heard only in the left speaker. Similarly, with headphones, you can blend the zones in both headphones or separate them with the two headphone outputs.

Extra Enjoyment with Play-Along Backing Tracks

The HP-307 is packed with a library of play-along songs, from classical to jazz. You can also play songs in a variety of formats, including commercially available SMF music files or audio files stored on your USB flash memory (sold separately), and audio CDs*. With built-in songs and SMF music files, you can designate which parts to play back. Play an orchestra backing part and play the piano part on top of it with your right hand to create a powerful ensemble performance. Since you can alter the key and tempo independently, you can slow down the playback of songs you are learning, or change the key of the song depending on the vocal range. The possibilities are endless. You can also use the Center Cancel function to minimize the melody part on an audio CD, and play along with one hand. You can also jam or sing with your favorite band.
