Features
The PX-S1100, PX-S3100 and PX-S5000 models combine minimalist design with authentic sound and feel, and fit perfectly into any living space. As the world's most compact* digital pianos, they offer modern features and an optimised speaker system for greater playing enjoyment and flexibility. The PX-S1100 and PX-S3100 feature the Smart Scaled Hammer Action keyboard with digitally controlled mechanics. The PX-S5000 sets new standards in expression and playing feel with its Smart Hybrid Hammer Action keyboard – inspired by concert grand pianos.

The world's most compact* digital piano
Thanks to Casio's high-density technology with space-saving design and vertically mounted circuit board, the keyboard, speakers and other components have been significantly reduced in size – without compromising playability, sound quality or performance.

Multi-Dimensional Morphing AiR Sound Source
Lively sound [Acoustic Simulator]
The rich, harmonious sound of a grand piano is created by a combination of complex mechanics and the overtones of its approximately 230 strings, which are produced depending on how they are played. Casio's Multi-dimensional Morphing AiR Sound Source reproduces this sound in a detailed and natural way.
The overtone structure of each of the 88 keys gives the PX-S1100 / PX-S3100 / PX-S5000 a lively sound that is tailored to the integrated speaker system. Sympathetic resonances (damper resonance), damper noise and the subtle key action noise enhance the authentic grand piano experience.
Multi-Dimensional Morphing AiR
The tone colour of a note played on an acoustic grand piano changes depending on how the key is played and how long the note reverberates. Casio's unique Multi-Dimensional Morphing Technology produces subtle changes in volume and tone depending on the strength of the touch and the time, allowing you to express the entire range of playing styles from soft pianississimo to powerful fortissimo.
Multi-Dimensional Morphing Technology (volume, key pressure, time)
Many digital pianos use lossy sound data — similar to MP3 — which causes details in the original sound to be lost. Casio's AiR Sound Source, on the other hand, uses lossless audio compression: the sound is preserved in its entirety, enabling nuanced reproduction of diverse waveforms. The result is an expressive playing experience — just like an acoustic grand piano.

The speaker cone has been maximised in size to deliver powerful sound. For greater detail, especially in the high frequencies, mica, a high-quality reinforcement material used in audio technology, is employed. The special internal speaker structure also allows for a wide range of movement of the voice coil, resulting in greater sound volume and rich, resonant bass.
The improved reproduction of low and high frequencies results in a balanced sound—with an excellent sense of presence and localisation, just like an acoustic grand piano.
Smart Scaled Hammer Action Keyboard
The mechanism, whose hammer weight corresponds to that of a grand piano, has been greatly reduced in size. Despite the shallow cabinet depth of only 232 mm, the PX-S1100 and PX-S3100 offer the natural touch of a grand piano.
88-key digital scaling and hammer response
The 88 keys of an acoustic grand piano have different hammer sizes and weights, giving each key a different touch. Casio's 88-key digital scaling technology digitally controls the volume produced when each key is pressed. The timing of the sound, which varies subtly depending on the pitch, is adjusted to the type of touch by the Hammer Response function.
Key Off Response
The timing of the note's decay is digitally controlled based on the movement of the keys when released. When playing repeated notes, each note is clearly articulated, even if the key does not return completely to its original position. This provides accurate touch sensitivity that controls the onset of sound and the damping of a note, just as you would expect from an acoustic grand piano. In addition, the PX-S5000 features Key Off Simulator, which effectively expresses the various nuances in the duration and sound of notes based on the speed at which you release your finger from a key.
Key surface
The keys feel high-quality and are comfortable to use. The finely textured surface of the keys prevents slipping, and the keys feel comfortable on your fingertips even during long periods of use.
Compact mechanism with natural piano touch
Thanks to the reduced size of the mechanism, Casio has been able to develop the world's most compact digital piano. The hammers and other sound-related components are designed to be particularly space-saving, resulting in a slim case that still offers an authentic piano touch.
Compact hammer mechanism
Casio has developed a unique, compact hammer mechanism that optimises the hammer weight, centre of gravity and moment of inertia to achieve a balance between a gentle response when played softly and a dynamic response when played forcefully.
Hammer holder mechanism for more precise keystrokes
The hammer holder mechanism is designed to prevent excessive vibration and ensure stable upward and downward movement of the hammer, resulting in stable and precise keystrokes.
Smart Hybrid Hammer Action Keyboard
The PX-S5000 is equipped with the newly developed Smart Hybrid Hammer Action keyboard. This wood-hybrid keyboard is combined with the latest digital control technology to combine the authentic touch of a grand piano with the compact style of a digital instrument. The weight of the hammer is utilised in the same way as on a grand piano, so that the keyboard feels light when played softly and provides a greater sense of resistance when played loudly. The keyboard is also equipped with counterweights that balance the hammer mechanism and ensure smooth and stable movement even when played softly.
The difference in touch is influenced by the weight of the hammer on an acoustic instrument - each of the 88 keys on a grand piano has a different hammer size and therefore a different weight. Not only the weight of the hammer, but also the thickness and number of strings can vary, so that the touch varies greatly depending on the keyboard area.
To accurately reproduce the touch of a grand piano, 88-key digital scaling technology is used to change the volume of each key, and the hammer response function also adjusts the timing of the sound, which differs subtly for each key. As a result, the touch differs when playing each key, just like on a grand piano.
The Key-Off Response function digitally controls the timing of the decay based on the movement of the keyboard when the finger is released. When a note is played repeatedly, the tone is clearly pronounced each time, even if the key does not return completely to its rest position. This achieves better playability when connecting and separating played notes. The Key Off Response function can be set to three different levels to suit your legato and staccato playing styles.
The Key-Off Simulator helps to faithfully reproduce the difference in release time (the time from when the key is released to when the sound completely fades away) based on the speed at which the key is released.
The white keys are made of a hybrid material consisting of plastic and high-quality spruce wood – the same wood used for grand piano keys. A special coating gives them an ivory-like appearance and a pleasant, natural feel. The black keys are visually and tactilely based on ebony.
Real-time control
The PX-S3100 offers a wide range of DSP effects for sound design, a continuously variable pitch bend wheel and two freely assignable rotary controls for intuitive control of important parameters in real time. This creates dynamic sound progressions and expressive possibilities that go beyond acoustic instruments. The integrated arpeggiator automatically generates matching patterns based on the material being played. All settings are clearly displayed on the high-quality LCD display.
Wireless MIDI & Audio Adapter
The included WU-BT10 Wireless MIDI & Audio Adapter allows the PX-S1100, PX-S3100 and PX-S5000 to be expanded wirelessly. Using Casio's own protocol, which combines audio and MIDI data via USB, the world's first (in terms of wireless adapters that do not require an external power supply and can process both audio and MIDI - as of February 2021, according to a survey conducted by Casio) adapter enables you to play music from your smartphone, tablet or other device via the PX-S1100/PX-S3100/PX-S5000 speaker system and exchange MIDI data from the PX-S1100/PX-S3100/PX-S5000 with a smartphone, tablet or other electronic devices.
Despite typical Bluetooth latency, Casio's technology ensures stable connections and reliable playback, e.g. with the Casio Music Space app.
