Roland's acclaimed SuperNATURAL Piano Sound Engine evolves with Acoustic Projection technology — an innovative, multi-dimensional sound system built into the new HP507. Acoustic Projection is inspired by the flagship V-Piano Grand and its ability to reproduce the natural sound field of an acoustic piano. The marriage of Roland's world-leading technologies in the HP507 empowers pianists with a complete, immersive acoustic-piano experience.
