The AP470 digital piano bridges the gap between digital convenience and authentic grand piano artistry with its sophisticated European and American grand piano tones. This elegant instrument features Casio's Multi-dimensional Morphing AiR Sound Source technology, which meticulously simulates the complex resonance phenomena that occur when all 88 keys interact or when the sustain pedal is engaged, capturing the nuanced reverberations that define a true grand piano's character. The AP470 achieves remarkable dynamic expression, reproducing everything from the most delicate pianississimo (ppp) passages that conventional digital pianos struggle to convey, through to commanding fortissimo (fff) performances. The acoustic lid design further enhances the instrument's authentic sound projection and visual appeal, making it the perfect choice for serious pianists seeking professional-grade performance capabilities. Two distinct world-class grand piano voices are built into the AP470, each carefully selected for different musical applications and performance settings. GRAND PIANO 1 provides rich, powerfully reverberating tones that respond beautifully to keystroke dynamics, making it ideal for classical repertoire and expressive solo performances. GRAND PIANO 2 offers bright, luxuriant sounds with crisp clarity that cuts through ensemble playing, perfectly suited to jazz and contemporary pop styles where presence and definition are essential.
