SuperNATURAL Piano Engine
The HP-503 incorporates Roland’s SuperNATURAL Piano technology for seamless velocity response, natural note decay, and authentic key-range behavior to reproduce perfect piano sound and expression. Tone color changes seamless in response to touch, accurately translating the player’s emotions. Tone decay is natural and organic, with the decaying sound not only decreasing in volume, but also gradually changing in color to a softer tone. Each note has its own character, which creates variations in tonal color and resonance of each note.
Authentic Fortepiano Tones Onboard
In addition to the selection of onboard grand-piano sounds, the HP-503 features a newly added Early Piano category containing four fortepiano variations and two harpsichord variations. Masterpieces composed by maestros such as Mozart, Beethoven, and Chopin can be played with the original sounds from the period. The appreciation and understanding for the piece is heightened when using the instrument that was actually used by the composers. You can also play these early piano sounds with built-in historic temperaments which are ideal to play with other classical instruments.
Ivory Feel-S Keyboard with Escapement
The HP-503 features new Ivory Feel-S Keyboard with Escapement. With the same progressive hammer action and escapement as the top-line PHA III, it offers unmatched expression and performance authenticity, capable of transforming the most subtle finger nuances into sound. It also provides incredibly fast key-repetition action. The surface of each white key replicates the unique appearance and comfortable feel of real ivory keys. The keys are constructed of a one-piece proprietary material that provides excellent moisture absorbency.
Progressive Damper Action Pedal
The HP-503 is equipped with “Progressive Damper Action Pedal” that have light resistance at the beginning of the stroke and more resistance the instant they begin to take effect, just like real acoustic pianos. This makes it easy for the performer to know when the pedal begins take effect, and also allows half-pedal techniques for subtle control of aftertones and resonance. This pedal can accurately convey the techniques of serious pianists.
Built-In Audio/MIDI Recorder with Flexible Control
The built-in recorder lets you capture your performances as audio and/or MIDI data — a convenient feature for pianists as well as students who want to evaluate their playing. Transpose, Tempo Change and Center Cancel controls are available for Audio data. Recorded audio data can be saved onto USB Memory, and copied to an external computer for making audio CDs or for uploading to the Internet.
*USB memory is required for audio recording.

The simple and intuitive control panel affords quick and easy access to the HP-503’s numerous features and applications. LCD panel provides the ideal visual interface with the instrument.
