Carefully selected tones

Explore the CT-S1’s range of 61 carefully selected tones, from
ADVANCED TONES, which fully utilize the AiX Sound Source,
which will take you on a trip down memory
lane through CASIO’s history.

Horizontal Bass Reflex System

Expect the unexpected — behind the compact frame lies
a powerful and clear sound thanks to the new bass-reflex
mechanism, bringing out the potential of each single tone.


You can enjoy expanding your acoustic experience through its
sleek body whenever you play or listen to your favourite music.

Touch Response

As responsive to touch as a piano, the keys absorb your emotion
and articulate it perfectly.

Tone Memory

You can register your favourite settings, including pre-set tones,
layers and reverb types, and access them quickly when you wish to
play specific music or songs.

Simple user interface

With intuitive operation, you can
select 7 main tones, including
piano and organ, and 4 tone
variations (Standard, Advanced,
Modern, Vintage) for each.


Perform anytime and anywhere you like — conveniently sized to be
easily portable, the CT-S1 can be powered by batteries, making
playing stress-free and enjoyable, just as music should be.

Chordana Play app

Practice your favourite songs anytime
and anywhere. Choose from the
50 built-in demo songs, or use the
downloaded MIDI files to expand
your playing repertoire. Once you’re
finished, check your progress with the
Chordana Play app.

Audio Adaptor (sold separately) and use
your smart device to play your music
through the CT-S1 speaker system.
