App "CASIO MUSIC SPACE"
Discover with the app "CASIO MUSIC SPACE" a variety of features that expand the graphical editing of the instrument’s functions 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 indicator lights.
Wireless MIDI & Audio Adapter
Use the supplied "Wireless MIDI & Audio Adapter (WU-BT10)" to connect wirelessly to 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 expression 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 sound but also reproduces changes in resonance and gently adjusts its effect depending on how deeply the pedal is pressed, allowing for sensitive expressive playing.
The soft pedal not only controls volume but also provides a more natural change in tone color, expanding expressive options in quieter passages. The slim AP-S450 features a continuously adjustable damper pedal. This design allows the decay characteristics of notes to change depending on pedal depth, enabling fine and nuanced musical expression.

Comfortable and Stable Piano Bench
Besides its elegant appearance, this piano bench offers high-quality features such as sturdy legs with non-slip rubber, a smooth, precise spindle mechanism for height adjustment, and a durable, comfortable seat covered in velour. The sophisticated spindle mechanism with a double-scissor system guarantees smooth and extremely long-lasting height adjustment. Small details like the rubber stoppers between the base frame and the support frame set this attractive piano bench apart from others in this price range.

Headphones
The Pronomic KH-900 is a professional stereo headphone that combines excellent sound characteristics with maximum wearing comfort at a budget-friendly price. The soft, wide synthetic leather headband automatically adapts to head size, providing a comfortable fit. The KH-900 offers an extensive frequency range from 15 to 25,000 Hz, delivering balanced, nuanced sound with brilliant, clear highs and precise, rich bass. Thanks to the low impedance of only 32 ohms, the KH-900 performs impressively even with very low-powered headphone outputs, such as those on MP3 players or smartphones, delivering powerful sound and enough headroom. The 3.5 mm stereo jack plug ensures excellent transmission properties. A 6.3 mm stereo jack adapter is also included.

Piano Method
This method introduces beginners to the instrument in a playful, relaxed way. Starting with familiar, simple melodies and progressing to two-handed playing of complete songs, it also conveys a fair amount of theoretical knowledge alongside the exercises. Reading notation, rhythm, dynamics and much more are covered in conjunction with the exercises. The straightforward exercises also guarantee quick learning success.
