Slim & Stylish Portable Design

Interface easy to use for everyone

The CT-S300 features a simple, intuitive interface, offering an organized layout with fewer buttons by using both a full dot LCD screen and dial. It is also equipped with a home button that lets users return to the original screen at any time, making for a superior multi-function keyboard with enhanced usability.

Interface easy to use for everyone

Sound no one would expect from such a compact keyboard

The use of 13 cm x 6 cm oval speakers with strengthened magnets delivers surprisingly great sound for such a compact instrument. An additional function that optimizes the equalizer in tandem with the volume provides balanced sound from the bass to the highs, even at low volumes.

Dance Music Mode and Voices expand ways to enjoy playing

The CT-S300 includes a mode that lets users put together drum, bass, and synthesizer phrases to easily enjoy dance music, as well as 12 types of Dance Music Voices that sound great with dance music. Just press along with the rhythm to add accents to ordinary playing and enjoy dance music.

Piano-Style Keys & Touch Response

The keys are built in a box shape like a piano. Touch Response delivers piano-like changes in volume and tone depending on the force used to play the keys.

My Setup Button

Register your favorite settings to easily recall tones and rhythms such as those learned in music class when you practice at home.

Pitch Bend Wheel

The pitch bender wheel makes it easy to add realistic sounding guitar choking, sax bending, and other effects to keyboard play.

Pitch Bend Wheel

USB to host micro B for expandability

The CT-S300 comes with a USB to host micro B jack that allows you to enjoy making music easily, together with your smart device or computer. (Commercially available cable required.)
