App "Casio Music Space"
Discover with the "CASIO MUSIC SPACE" app a variety of functions that expand the graphical editing of the instrument’s features and enhance your piano experience.
Visual Information Bar
The "Visual Information Bar" on the front provides visual confirmation of playing speed, pedal operation, tempo, and beat through illuminated indicators.
Wireless MIDI & Audio Adapter
Use the included "Wireless MIDI & Audio Adapter (WU-BT10)" to establish a wireless connection with your smart device and enable audio playback through the instrument’s sound system as well as MIDI data communication.

Pedals
Discover a new realm of expressive possibilities with the carefully crafted pedals of the AP-S450. These pedals are designed to capture the authentic feel and nuances of a grand piano. The damper pedal not only sustains the sound but also reproduces changes in resonance and gently adjusts its effect depending on how deeply the pedal is pressed, enabling sensitive expression in your musical performance.
The soft pedal controls not only volume but also offers a more natural change in tone color, expanding expressive possibilities in softer passages. The sleek AP-S450 features a continuously adjustable damper pedal. This design allows changes in the decay of tones depending on pedal depth, enabling fine and nuanced musical expressions.
Comfortable and Stable Piano Bench
This piano bench offers high-quality features alongside its elegant appearance, such as sturdy legs with non-slip rubber, a smooth, precise spindle mechanism for height adjustment, and a durable, comfortable seat covered in corduroy. The sophisticated spindle mechanism with a double scissor system guarantees smooth and extremely durable height adjustment. Small details like rubber stoppers between the base frame and support frame clearly distinguish this beautiful piano bench from others in this price range.
Comfortable Stereo Headphones
The KH-238 delivers full, balanced sound with rich bass reproduction and clear highs. It offers plenty of volume while maintaining clean and precise stereo imaging. Naturally, the softly padded, wide headband is length-adjustable. The extension offers 12 steps on each side for optimal fit. For even more wearing comfort, the ear cups are mounted on two-axis swivels. The thick, soft padding of the circumaural ear cups also provides good external noise isolation. The integrated volume control in the cable is always at hand, simplifying use with a PC or mp3 player. The 3.5 mm stereo jack plug delivers excellent transmission properties, and an adapter to 6.3 mm stereo jack is also included.
Piano School
The instrument is introduced and explained to beginners in a playful, relaxed way. Starting with familiar, simple melodies up to playing complete songs with both hands, various theoretical knowledge is also conveyed alongside. Reading notes, rhythm, dynamics, and much more are covered alongside the exercises. Additionally, the simple exercises guarantee quick learning success.
