The characteristics of CASIO’s newly developed Multi-dimensional Morphing AiR* Sound Source reflect thorough attention to detail in expressing the rich, resonating tones inherent to the piano. The capacity of the installed memory has been expanded to achieve a longer sampling duration and enhanced waveform data quality. The temporal changes in tone that create sound you would expect only from a piano, beginning with the initial sound and leading into a beautiful extension until the sound eventually vanishes, are reproduced naturally.
