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 and delivers a natural tonal character as well as a 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 with 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 distinct tonal 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, expressive piano sounds generated from a wide range of signal variations.
Tonal Colors
19 built-in instrument voices, including the elegant and flattering concert grand tone, and the wide range of dynamic expression options are appreciated by pianists around the world.
Acoustics
Featuring a 2-channel sound system with two speakers that recreates the natural resonance of a concert grand. The "Volume Sync Equalizer" lets you balance the sound across all frequencies even at low volume—ideal for late-night practice or quiet moments. The "Sound Mode" function lets you expand the device's audio with various effects for a customized piano experience. Even when using headphones, enjoy a natural, room-filling 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 highly expressive playability and a touch response that varies with the intensity and speed of your performance. The white keys feature an ivory-like surface texture, while the black keys resemble ebony. This provides a premium, comfortable playing feel even during extended sessions. The timing and nuances of sound damping can be varied not only by the speed of your key attack but also by how you release the keys, making your playing even more expressive.
Pedals
The shape and spacing of the pedals emulate a concert grand and have been optimized for outstanding playability and stable pedal control.
Experience
Wireless MIDI & Audio Adapter
Use the included "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.
App "CASIO MUSIC SPACE"
Explore a wide range of functions for graphical editing of instrument settings. The "CASIO MUSIC SPACE" app enhances your piano experience.

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

Headphones
The Pronomic KH-900 is a professional stereo headphone that combines excellent sound characteristics with top-level wearing comfort at an affordable price. The soft, wide synthetic leather headband automatically adapts to head size to ensure a comfortable fit. The KH-900 offers a wide frequency range from 15 to 25,000 Hz, delivering balanced, nuanced sound with brilliant, clear highs and precise, rich bass. With a low impedance of only 32 ohms, the KH-900 performs powerfully even on low-power headphone outputs such as MP3 players or smartphones. The 3.5 mm stereo jack provides excellent signal transmission, and a 6.3 mm stereo adapter is included.
