Portable 61-Key Arranger for All Skill Levels

The Casio CT-S400 Casiotone is a 61-key electronic keyboard with touch-responsive keys designed for players at any level. It delivers 600 tones and 200 rhythms in a lightweight 4.98 kilogram frame that runs on batteries or the included 120 volt AC adapter. Built-in stereo speakers provide immediate sound without extra gear.

Battery Power and MIDI USB for Flexible Setups

Because it operates on battery power, the instrument fits into mobile practice sessions, street performances or classroom circles where mains power is unavailable. The MIDI USB connector links directly to computers or tablets for recording and notation work, while the headphone jack enables silent rehearsal without disturbing others. No audio interface or mixer is required for basic connection.

Chordana Play App Expands Learning Tools

The supported Chordana Play software adds interactive lessons, MIDI file playback and real-time scoring that extend the onboard 5-track recorder. Bluetooth connectivity lets the keyboard communicate with the app wirelessly, removing cable clutter during practice. The LCD display keeps rhythm, tone and function settings visible while the app handles deeper editing.
