PX-S1100MB
Introducing two new limited‑edition colours-Calm Blue and Mellow Beige-for the Privia PX‑S1100. The PX-S1100 is well known for its slim profile, authentic keyboard touch and rich expression. Based on the concept of “CALM & MELLOW” (moments of tranquillity and ease), these special new colour variations make it even easier to incorporate the piano as part of a routine that soothes the mind. Moving beyond the classic black, white, and red finishes, these new colours reflect Casio’s “In Harmony with Life” philosophy — blending individual lifestyle and musical expression in perfect balance. The Mellow Beige edition introduces a soft, warm finish with green felt accents inspired by indoor plants, creating a relaxed and welcoming atmosphere. The Privia PX-S series is celebrated for its slim, contemporary design and authentic sound, offering rich expressiveness with a natural key touch in a compact form.
Offers high‑quality sound and touch, all in the world’s most compact body.*
The keyboard mechanism, speakers and other components have been miniaturized as far as possible while still delivering the highest performance. Crucial to the keyboard's small size is Casio's proprietary high-density technology, featuring a space-saving internal structure with the circuit board mounted vertically. These innovations and others have made possible the world's slimmest* digital piano in terms of depth – allowing for extremely flexible placement.

The following is from our interview with pianist Hayato Sumino (Cateen):
“While the Privia PX‑S1100 delivers beautiful tone, its natural touch really stands out. When you play you can express everything from delicate pianissimo to powerful fortissimo—and truly feel the joy of producing a great sound, much like playing a grand piano.”

Sound Samples
Keyboard
- Features the “Smart Scaled Hammer Action Keyboard” that combines a mechanical hammer action with digital control that delivers nuanced touch and expressive performance across dynamic ranges and registers.
- The white keys feature an ivory‑style textured finish, whereas the black keys have an ebony‑style texture that creates a premium feel that’s comfortable even during extended periods of play.
- The tone isn't affected just by how you press the keys; how quickly you release them also influences the nuance of both damping and resonance.
- 88-Key Digital Scaling technology means that volume is individually controlled for each key in response to how hard it is played, with the touch weight varying along the length of the keyboard, like a grand piano.
- The hammer response adjusts the timing of the production of sound according to both register and playing style, which provides the sensation of playing a grand piano.
- The key‑off response allows for fine control of either legato or staccato touch articulation, so you can tailor how notes connect or detach for precise expression.
Pedals
- Essential for piano performance, the supplied SP-3 damper pedal can be connected to the PEDAL UNIT jack. For greater expressive control, the SP-34 three-pedal unit (sold separately) with a continuously variable damper pedal, can be connected.
EXPERIENCE
Expand your musical experience. The Privia offers possibilities beyond just playing the piano to let you enjoy music to the fullest.
- Digital effects, including Sound Modes, Chorus, Brilliance and other DSP effects, add depth and space to sounds.
- Layer function for layering of two different tones, and Split function for splitting the keyboard between lower and upper zones with a bass tone assigned to the lower zone and a freely assignable tone for the upper zone.
- Duet function for splitting the keyboard into two zones of the same register.
- Built-in MIDI record/playback and metronome functions for practice sessions.
- Part on/off function allows you to mute the right- or left-hand part of song data saved in the user area of the digital piano or USB flash drive. Great for practising each part separately. (Note that the effectiveness of this feature depends on the song data.)
- Two headphone jacks allow for up to two pairs of headphones to be connected for private listening.
Wireless MIDI & Audio Adapter (WU-BT10)
- Connect the included Wireless MIDI & Audio Adapter (WU-BT10) and listen to music from your smartphone or tablet through the PX-S5000 speaker system.
- Compatible with Bluetooth® Low Energy MIDI devices allowing you to use the PX-S5000 as a wireless MIDI controller keyboard, for example.
