Casio CT-S300 Keyboard — Portable 61-Key Arranger with Touch Response

The Casio CT-S300 is a slim 61-key portable keyboard built for beginners and hobbyists who want expressive play without the bulk of a full arranger workstation. Weighing just 3.3 kg and measuring 930 mm × 256 mm × 73 mm, this Casiotone model is roughly 30% smaller in volume than the older CTK-3500 while still delivering 400 tones, 77 rhythms, and a touch-responsive keybed. The CT-S300 is the right choice for learners who need a battery-capable keyboard that travels easily between home, classroom, and stage.

What Sets the CT-S300 Apart in the Beginner Tier

The integrated pitch bend wheel adds expressive guitar choking, sax bending, and other real-time inflections — a rare inclusion on sub-€200 keyboards. Dance Music Mode combines 50 dance patterns with 12 dedicated Dance Music Voices, letting players build drum, bass, and synth phrases by pressing along with the rhythm.

Keybed, Sound Engine, and Connectivity Specs

Specs translate directly into real playing situations, from bedroom practice to street busking.

• Keys: 61 velocity-sensitive, box-shaped piano-style keys — Touch Response with 2 sensitivity levels shapes dynamics like an acoustic piano.
• Polyphony: 48 notes — Headroom for layered accompaniments and split voices without notes dropping out mid-phrase.
• Sound Library: 400 tones, 77 rhythms, 60 preset songs — Broad palette with one-touch presets that auto-pick the right sound for each rhythm.
• Speakers: 2 × 2.5 W with 13 cm × 6 cm oval drivers — Volume Sync EQ keeps tone balanced from bass to highs even at low volumes.
• Connectivity & Power: USB to host (micro B), 3.5 mm headphone jack, audio in, sustain pedal jack, AA × 6 alkaline (approx. 19 hours) or AD-E95100L adapter — MIDI to a computer, silent headphone practice, or a full day of lessons on one battery set.

Beginners, Students, and Mobile Players

The CT-S300 fits players who want real instrument feel without committing to a heavy 88-key setup. First-time learners benefit from touch-sensitive keys, Chordana Play app compatibility, and 60 built-in songs that structure practice, while music students can carry it between lessons thanks to the 3.3 kg chassis and roughly 19-hour battery life. The CT-S300 is the right choice for anyone stepping up from the non-velocity CT-S100 who needs expressive dynamics and a pitch bend wheel at an accessible price.
