The acoustic level achieved by a

digital piano is determined by the

capacity of the memory that stores

sounds after sampling. A new high-

capacity memory, boasting a capacity

of approximately three times in

excess of our previous models, is the

foundation of our Multi-Dimensional

Morphing AiR Sound Source.

The waveform data sampling capacity

has increased dramatically, enabling

natural reproduction of the delicate

changes in waveforms associated

with concert grand pianos. The sound

quality and resonance have evolved

dramatically, now having the ability

to produce simultaneous sounds

comprising of up to 256 notes in our

high-end models (PX-860, AP-650M,

AP-460).

Digital pianos normally compress and

record sound waveform data in their

built-in memory. This data is then

expanded and played back when

recalled. This process is similar to the

compressed audio data in MP3 ﬁles,

and similarly, the replayed sound suffers

from digital deterioration in comparison

with the original sound.

The advanced Lossless Audio

Compression technology adopted for

CASIO’s Multi-Dimensional Morphing

AiR Sound Source has made it

possible to reproduce sounds without

this deterioration of the original sound

quality. Quite simply, this reproduces

musical performances with acoustics

that are immeasurably closer to natural

piano sounds.
