The Roland Digital Piano HP103 features rich resonance and wide-ranging expressiveness. The stereo sampling piano sound generator realistically reproduces even the sound of the hammers striking the strings, producing the tones of a high-quality concert grand piano. Maximum polyphony of 64 notes ensures that you can use the pedal freely without running out of notes. In addition, this instrument features a “Grand Sound” speaker system, and simulates the full, three-dimensional nature of a concert grand piano (Grand Space), which together help to deliver a sound with even greater clarity and power (Dynamic Emphasis).
