Compact 61-key instrument

The Casio CT-S1 is a portable keyboard built for players who want a full 61-key range in a minimal footprint. Its simplified front panel keeps the focus on tone selection and performance, making it suitable for practice, lessons or casual playing at home.

Built-in speaker system and headphone output

The bass-ported stereo speakers deliver clear sound across the entire volume range without external amplification. A headphone jack allows private practice, and the unit runs on USB power so no separate mains adapter is required for typical use.

Upgrade from basic controllers or smaller keyboards

Musicians moving up from mini-key controllers or entry-level models gain a full-size keybed and the AiX sound engine with concert grand piano tone. It is not for players who need weighted hammer action, extensive onboard sequencing or professional stage connectivity.

Questions about this item

How do I connect the CT-S1 to a computer or tablet for use with the Chordana Play app?

Plug a micro USB cable into the keyboard's port and the other end into your PC, Mac, iOS, or Android device; no drivers or installation are required.

What upkeep does the CT-S1 keyboard require over time?

The unit has no user-serviceable parts; keep the keys and speaker grilles free of dust with a soft, dry cloth and avoid liquid cleaners.

At what point does the built-in speaker system reach its limit during extended playing sessions?

The bass-ported stereo speakers maintain clarity across the full volume range, but sustained maximum output will eventually hit the physical limits of the compact enclosure.
