Concert grand piano sample
At the heart of the AP-300 is the new Concert Grand Piano sample, designed to replicate the complex sound of an acoustic grand piano. It captures the subtle overtones and rich resonance, creating an authentic playing experience. Whether you're playing soft passages or powerful chords, this sample delivers an immersive sound that is both detailed and dynamic.
Advanced key action for realistic performance
The Smart Scaled Hammer Action on the AP-300 offers a highly realistic feel, with each key individually weighted and digitally scaled to replicate the response of a traditional grand piano. This allows for nuanced and expressive performances, making it ideal for both beginners and experienced pianists alike. The precision of the key action ensures that every note is captured with emotion.
Modern controls and connectivity
The AP-300 is equipped with touch panel controls, a feature unique at this price point, making it easy to navigate settings and adjust functions. Additionally, the built-in Bluetooth Audio and MIDI provide wireless connectivity for streaming music or integrating with apps. This combination of modern technology and classic design elements enhances the overall experience for players.
USB audio recording and playback
The piano’s USB Audio Record and Playback function lets you easily capture your performances in high-quality WAV or MP3 formats, making it convenient to record, share, or review your music. USB connectivity ensures smooth interaction with other devices, and the 2-track MIDI recorder allows for more advanced compositions, giving you full control over your musical creativity.
Touch panel controls
The Casio AP-300 features touch panel controls, providing an intuitive and modern way to interact with the piano’s settings. These controls allow for quick adjustments to tones, volume, and other functions without the need for traditional buttons. The sleek design of the touch panel complements the piano’s minimalist aesthetic while making it easier for users to navigate and customise their playing experience effortlessly.
Casio Music Space
Casio Music Space is a free app designed to help Casio digital piano and keyboard players get more out of their instrument. When connected to a compatible Casio model, it acts as a digital score, practice tool, and performance companion, all in one place.
Features like the Piano Roll make it easier to see which notes to play, even if you’re not confident reading music, while the Score Viewer lets you follow sheet music and listen along at the same time. There’s also a Music Player for practising with your favourite songs, plus a Live Concert Simulator that adds audience and environmental sounds to recreate the feel of performing live. You can adjust tempo, repeat tricky sections, record your progress, and even control piano settings directly from the app. It’s a thoughtful, user-friendly way to practise, learn, and enjoy playing at your own pace.
