Celviano AP-300: A Model Designed for a Great Start in the Range

The Casio Celviano AP-300 is aimed at beginner to intermediate pianists looking for an elegant furniture-style piano, easy to handle but sufficiently versatile to accompany the first years of practice. Its approach emphasizes realistic touch, musicality of piano sounds, and clear educational functions, while maintaining modern connectivity for easy playing, learning, and recording.

Keyboard Design

With its 88-key graded hammer action keyboard, the AP-300 reproduces progressive resistance (heavier keys in the bass than in the treble) to mimic the feel of an acoustic piano. The touch sensitivity is finely adjustable with 5 levels (plus off), complemented by a hammer response on 10 levels (plus off) to adjust dynamics and the initial sound sensation. The ivory and ebony textured keys improve grip, while the key release response (3 levels), the key release simulator, and the 4 "piano position" types refine realism according to your playing style.

Sound Quality

The AiR Morphing multidimensional engine delivers rich and nuanced tones, with 19 voices including several grand pianos, upright pianos, organs, and strings. The maximum 192-note polyphony ensures excellent chord sustain, even with the damper pedal. To enhance the "acoustic" behavior, you have settings for string resonance (4 levels plus off), damper pedal resonance (4 levels plus off), key action noise (4 levels plus off), and a lid opening simulator (4 levels). The 2 x 20 W amplification and 2 x 12 cm speakers provide balanced projection, with an optimized headphone mode for natural listening during silent practice.
