Casio PX-S1100 MB Stage Piano: Slim, Smart, and Ready to Gig

The Casio PX-S1100 MB is a limited-edition Mellow Beige version of Casio's flagship Privia stage piano, built for players who need a full 88-key weighted action in the slimmest, lightest package on the market. The proprietary Smart Scaled Hammer Action keyboard and AiR sound engine reproduce the touch and tone of each individual note. The Mellow Beige finish softens the gloss-topped unibody chassis for modern interiors and on-stage setups.

What Sets the PX-S1100 MB Apart

Two design choices distinguish this instrument in the portable stage piano category. The Smart Scaled Hammer Action keyboard uses a proprietary key-scaling system that varies the weight of each of the 88 keys, mimicking how an acoustic grand feels heavier in the bass and lighter in the treble. Bluetooth audio via the included WU-BT10 USB adapter streams backing tracks wirelessly through the built-in stereo speakers.

Smart Scaled Hammer Action Keyboard

Casio's Smart Scaled Hammer Action system varies resistance across all 88 keys to mirror an acoustic grand, while ebony and ivory-feel textures provide grip during fast passages.

• Keys: 88 — full concert range for classical repertoire
• Action: Smart Scaled Hammer Action — per-note weighted scaling that mirrors acoustic grand feel
• Velocity Curves: 6 selectable — match response from soft classical to aggressive lead playing

AiR Sound Engine with 192-Note Polyphony

Casio's AiR sound engine samples each note individually and layers physical-modeling elements such as damper resonance, string resonance, hammer response, and key-off simulation.

• Polyphony: 192 notes — handles layered passages and sustained pedal work without cutoff
• Onboard Tones: 18 — stereo grand piano, electric pianos, organs, strings, vibraphone, harpsichord, bass
• Resonance Modeling: Damper, string, hammer response, key-off — physical-modeling layers add acoustic realism

Bluetooth, USB Audio, and Battery Power

Built for life on the move, this stage piano streams music wirelessly via Bluetooth, while the class-compliant USB port supports MIDI and audio recording to a flash drive.

• Bluetooth: Audio via included WU-BT10 USB adapter — wireless streaming of backing tracks and learning apps
• USB Port: Class-compliant MIDI + audio recording to flash drive — capture performances without a computer
• Power: AC adapter or 6 AA batteries — play anywhere, even without mains power
• Weight: ~11 kg (under 25 lbs) — easy to carry to gigs and rehearsals

Who Should Choose the Casio PX-S1100 MB

The Casio PX-S1100 MB is the right choice for gigging keyboardists, serious piano students, and home musicians who need authentic grand-piano feel in a portable, stage-ready instrument. Its slim chassis and battery operation suit touring players, while the weighted action and AiR sound engine satisfy players who demand realistic touch and tone. Built-in speakers, dual headphone jacks, and the 60-song music library with lesson mode also fit apartment practice.
