SuperNATURAL Piano


Refined Piano Performance in a Stylish, Compact Cabinet

Its sound and touch is a result of our relentless pursuit of the characteristics of grand pianos. Its minimalistic and modern design is true to acoustic pianos. The HP-305 is the standard model in the HP series, and all of its elements have been made compact. Its special speaker system reproduces the sound generated by the SuperNATURAL Piano sound engine as a clear and spatial sound to allow players to give beautiful and smooth performances true to grand pianos. Players can enjoy performances to their hearts’ content on the PHA II Ivory Feel keyboard (with escapement) which provides a natural texture and tactile feel. The Classic Position lid and three pedals with traditional design make playing easier, and enhance its piano-like appearance. It also comes with a metronome and 3-track recorder function, and can playback a variety of songs so you have all you need to support your progress. Playback your favorite built-in songs with accompaniment, commercially available music files, and music CDs to make your practice more enjoyable.

SuperNATURAL Piano

The HP-305 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.

PHA II Ivory Feel Keyboard with Escapement

For the most authentic acoustic grand piano feel, the HP-305 is equipped with the new PHA II keyboard with Escapement. This amazing keyboard technology offers the same natural response as a grand piano, with a heavier touch in the lower range and lighter touch in the upper, and with lighter resistance on pianissimo passages and stronger resistance on fortissimo just like a well-maintained acoustic grand. It even faithfully reproduces the escapement “click feel” of a grand-piano action. 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-305 is available in gorgeous wood cabinets with a traditional rosewood finish, cool satin black finish, or the beautiful, luxurious Polished Ebony finish. The HP-305 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.

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 new HP-305 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.
