Casio CT-S1 76 Black

A Modern Casiotone: More Keys, Same "Plug and Play" Philosophy

With the CT-S1-76, Casio extends the spirit of compact, play-oriented keyboards: a sleek design, direct controls, and an instrument that fits equally well in a living room or a studio corner. The upgrade to 76 keys offers immediate comfort for arrangements, richer left-hand parts, and accompaniments, while maintaining the series' core approach: immediately musical sounds, quick handling, and unrestricted mobility.

Keyboard Design

The CASIO CT-S1-76 features a 76-key keyboard with a light touch, designed to switch seamlessly between styles (pop piano, funk, electro, accompaniment). The 3 sensitivity levels allow you to tailor the response to your playing: more precise attack, easier nuance control, and better velocity management, whether playing arpeggios, block chords, or melodic lines. Its slim format optimizes space, a real plus for transport and small areas.

Sound Quality

The sound section is based on AiX technology, designed to deliver detailed and lively reproduction, with expressive timbres and strong presence in the mix. The 61 tones cover essential musical sounds: acoustic pianos, electric pianos, organs, synthesizers, and vintage hues to vary colors both in rehearsals and at home. The 64-note polyphony ensures solid chord sustain and dense passages. On the output side, the Horizontal Bass Reflex system enhances the bass sensation and provides a wider sound despite the compact format, powered by 6.5 W + 6.5 W amplification.

Built-in Effects

To quickly shape your sound, the CT-S1-76 offers essential and effective effects: Reverb for depth, Chorus for width, and Delay for space and relief, especially appreciated on electric pianos, organs, and synth sounds.
