The Casio Celviano AP-300 is an 88-key console digital piano with Smart Scaled Hammer Action keys, Multi-Dimensional Morphing AiR sound, a 2-speaker system (16 W + 16 W, max 20 W + 20 W), and a furniture-style cabinet with soft-close key cover and opening top lid. North American packages typically include a matching height-adjustable bench and the WU-BT10 Bluetooth MIDI & audio adapter. Sound and Touch AiR morphing delivers concert-grand piano tones with adjustable string resonance, damper resonance, key action noise, and lid simulation. The Smart Scaled Hammer Action keyboard uses 88-key digital scaling so each key's hammer response tracks a grand piano more closely than a single uniform weight curve.
