The Essence of a Grand Piano!
With the AP-300, you can experience the design and acoustic presence of a grand piano. The AP-300 piano adopts the sound philosophy of the Celviano top models, offering a natural tone and realistic playing feel.
Sound
Sound Source
The natural and powerful resonance of a concert grand thanks to the "Multi-Dimensional Morphing AiR Sound Source." Discover how tonal nuances and timbres change depending on playing speed and touch thanks to "Multi-Dimensional Morphing." Dive into the sonic depth of a concert grand with the "String Resonance System." Experience the authenticity of a concert grand thanks to the "Mechanical Sound System," which simulates various mechanical noises of the instrument. Switch between four different sound variations with the "Lid Simulator," corresponding to opening and closing the large piano lid. Thanks to "Lossless Audio Compression," the original audio quality is preserved during compression. The result is beautiful and expressive piano sounds generated from a wide range of signal variations.
Timbre
19 built-in instrument sounds, including the elegant and flattering concert grand piano tone, as well as a broad range of dynamic expression options, are appreciated by pianists worldwide.
Acoustics
Featuring a 2-channel sound system with 2 speakers that replicate the natural resonance of a concert grand. The "Volume Sync Equalizer" allows balanced sound adjustment across all frequencies, even at low volume. This is especially practical for late-night practice or quiet moments. The "Sound Mode" function lets you enhance the sound from the audio system with various effects—for a personalized piano experience tailored to your taste. Even with headphones, enjoy a natural and spacious sound thanks to the specially tuned "Headphone Mode."
Playability
Keyboard
The "Smart Scaled Hammer Action Keyboard" combines hammer mechanics with digital sound control technology—for particularly expressive playability and a touch response that varies with the intensity and speed of your playing style. The white keys feature an ivory-like surface texture, while the black keys resemble ebony. This ensures a high-quality and comfortable playing feel, even during extended sessions. The timing and nuances of sound damping can be varied not only by the speed of key strike but also by the release, making your playing even more expressive.
Pedals
The shape and spacing of the pedals are modeled after a concert grand and optimized for excellent playability and stable pedal control.
Experience
Wireless MIDI & Audio Adapter
Use the included "Wireless MIDI & Audio Adapter (WU-BT10)" to establish a wireless connection with your smart device, enabling audio playback through the device’s sound system as well as MIDI data communication.
App "CASIO MUSIC SPACE"
Discover a variety of features for graphical editing of instrument functions. The "CASIO MUSIC SPACE" app enhances your piano experience.
Comfortable and Stable Piano Bench
This piano bench offers high-quality features alongside its elegant look, such as sturdy legs with non-slip rubber feet, 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 durable height adjustment. Small details like rubber stoppers between the base frame and support frame clearly set this beautiful piano bench apart 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. The softly padded, wide headband is length-adjustable with 12 steps on each side for optimal fit. For even more 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 on the cable is always within reach, simplifying use with a PC or mp3 player. The 3.5 mm stereo jack plug ensures excellent transmission quality, and a 6.3 mm stereo jack adapter is also included.
Piano Method
This playful and relaxed piano method introduces beginners to the instrument and explains it. Starting with familiar, simple melodies and progressing to two-handed playing of complete songs, it also imparts some theoretical knowledge along the way. Reading music, rhythm, dynamics, and much more are covered alongside the exercises. Additionally, the simple exercises guarantee quick learning success.
