Casio CT-S1-76BK — A 76-Key Portable Keyboard with Stage-Ready Tone

The Casio CT-S1-76BK extends the popular Casiotone CT-S1 line into a wider 6.3-octave range while keeping the ultra-portable footprint. At 1,140 x 258 x 83 mm and 5.3 kg without batteries, it slips onto a desk, a stand, or into a car for a gig. This keyboard suits musicians who need serious piano sound with modern connectivity in a backpack-friendly package.

What Sets This Model Apart in the Portable Keyboard Category

The horizontal bass-reflex speaker system pairs 13 cm x 6 cm drivers with 6.5 W + 6.5 W amplification for a low end that punches above the chassis size. Casio's AiX Sound Source powers 61 curated tones, including 12 Casio Classic Tones recreating the CZ-101, VZ-1, and VL-1 from the company's heritage. A dedicated Surround button widens the stereo image through the built-in speakers for an enveloping listening experience.

Velocity-Sensitive Keys That Reward Expressive Playing

Spring-loaded synth-style keys give this model a responsive, low-noise action suited to piano, organ, and synth parts. Three touch-response levels plus an off setting let players tune dynamics from a light synth feel to a weighted piano-style response. The 76-key range covers wide repertoire without the bulk of a full 88-key board.

• Number of Keys: 76 full-size keys — covers wide piano and keyboard repertoire
• Touch Response: 3 sensitivity levels + off — match the action to the playing style
• The spring-loaded synth-style keys offer a quiet and stable performance, while a subtle grain on the white keys prevents slipping during long practice sessions.

AiX Sound Source with 64-Note Polyphony

Casio's AiX engine analyzes harmonic content to recreate acoustic and electronic instruments in detail. With 64 notes of polyphony, layered performances and sustained piano passages stay clean without dropped notes. The 61-tone palette covers pianos, electric pianos, organs, strings, brass, synth leads, and pads, with 10 Advanced Tones responding dynamically to playing intensity.

• Sound Source: AiX — detailed harmonic modeling of acoustic and electronic instruments
• Maximum Polyphony: 64 notes — enough headroom for layered performances
• A carefully curated selection of 61 tones, including 10 Advanced Tones and 12 Casio Classic Tones, is provided instead of a massive, overwhelming sound bank.

Bluetooth, USB, and Battery Power for True Mobility

The rear panel hosts USB TO HOST micro-B for class-compliant MIDI to Mac, PC, iOS, and Android, plus USB TO DEVICE for the optional WU-BT10 Bluetooth adapter. A 3.5 mm stereo TRS audio input lets players jam along with backing tracks through the built-in speakers, while a 6.3 mm TRS pedal input accepts sustain footswitches. Power comes from the included AD-A12150LW adapter or 8 AA batteries for roughly 7 hours of cable-free playing.

• Wireless: Bluetooth MIDI & audio (via WU-BT10) — cable-free connection to apps and devices
• Audio Input: 3.5 mm stereo mini TRS — play along with phones, tablets, or mixers
• For added control, the 6.3 mm TRS pedal input allows you to connect sustain footswitches like the SP-3 or SP-20.

For Gigging Musicians, Students, and Home Players

This keyboard is the right choice for musicians who want one instrument that covers home practice, lessons, and small-venue gigs without hauling a heavy stage piano. Beginners benefit from the approachable control layout, the built-in metronome with 16 beat variations, and the one-button MIDI recorder for reviewing practice sessions. Semi-pro players get a reliable backup board with 61 gig-ready tones, a sustain pedal input, and Bluetooth MIDI for wireless control via the Casio Music Space app.

The Casiotone Heritage: From 1980 to Today

In 1980, the original Casiotone CT-201 made electronic music accessible to anyone regardless of skill level or budget. This Casiotone carries that legacy forward, blending four decades of sound design with modern connectivity in a chassis that fits a backpack.
