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 flagship models, delivering 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 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 with 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, along with a broad range of dynamic expression options, are appreciated by pianists worldwide.
Acoustics
Equipped with 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 handy 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 especially 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 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.
