Linear Morphing AIF* sound source reproduces wider than ever, more natural fortissimos and pianissimos. A world-famous brand concert grand piano was used to collect samples of tones produced by four optimum key pressures for each note. Next, morphing technology was used to modify the notes for continuity.

The result is naturally smooth transitions from delicate pianissimos to powerful fortissimos, which brings you a level of grand piano expression that until now was difficult to reproduce in a digital piano.

Using the damper pedal adds acoustic resonance, which is similar to that produced by the vibration of strings in a grand piano. The result is richer, more acoustically natural expressivity.

A new type of speaker system is designed and engineered to enhance the clarity and beauty of the tones produced by the new sound source. With the PX-730BK and PX-730CY, speakers are mounted underneath the piano, for a sound that is amazingly more expansive than that produced by previous speaker systems. This creates a natural acoustic space that enfolds the performer in a pleasant world of sound.

True and smooth grand piano level key action is reproduced using the actual weight of the hammer, without relying at all on springs. A Tri-Sensor Scaled Hammer Action Keyboard improves playing of successive notes, for a musical experience that is the next best thing to an acoustic grand. Of course, low notes play heavier and higher notes play lighter, just like an acoustic grand.
