Sounds to Inspire Your Playing

Redefining what makes a ‘real’ instrument, the CT-S400’s AiX Sound Source technology interprets the expressive complexity of musical instruments. With a rainbow of sounds to choose from, you never need to stop playing. Piano, strings, brass, synthesizer, bass and drums – 600 tones mean you are no longer restricted to one genre and the world of music is yours to explore.

Which one will inspire you today?

The Sound of a Great Time

Despite the CT-S400’s compact size, Horizontal Bass Reflex technology boosts the lows and, together with custom speakers, brings powerful and vivid sounds to life. Add the surround sound function and truly experience the vibration and power of pure music. Let the Volume-Sync EQ function take control as it automatically adjusts the balance between bass and treble, maintaining a punchy, vibrant sound, even at lower volumes. Touch the pleasure of sound and experience rich audio from the comfort of your home.
Now, that’s music to our ears.

Get Right to the Good Stuff

With only the essential buttons on the CT-S400’s console panel, and a large dial to select tones and change settings via the LCD screen, the familiar keyboard layout ensures an intuitive experience. Maximize inspiration with My Setup. Program in a range of functions to suit your needs. Assign your favorite settings to each of the 5 buttons underneath the LCD screen and easily access them again with a single touch as soon as you’re ready. Customize the CT-S400, and make your music about you.

You Play the Keys, Casiotone Brings the Band

The CT-S400 brings the ensemble to you. With 200 rhythmic patterns from a vast range of genres, you can play along to any of your favorite tunes. Replicate the exhilaration of playing alongside other musicians using the automatic backing function with any of the 160 built-in songs. Customize settings and make the performance your own by changing the tempo and selecting left-hand or right-hand parts to play along with and individually practice.
Maintain your enjoyment – it’s all about stress-free practice at your own pace.

A Musical Partner That Is Always Close at Hand

Powerful meets compact. The CT-S400’s slim design means it’s easy to move and set up anywhere. Make music in any location, with or without a stand or desk. Ideal – even when space is limited – thanks to the handy strap pins. The CT-S400 will always be by your side and ready to play.

Smart, Creative, and Connected to Your World

The CT-S400 offers countless ways to enjoy the thrill of music. Listen to the music from your smartphone or tablet through the powerful keyboard speakers by using the Wireless MIDI & Audio Adaptor WU-BT10*. Access the score of each built-in song with the CASIO MUSIC SPACE app. Customize melodies in Audio Mode by changing the key and tempo, or by using the ‘cancel melody’ and ‘cancel accompaniment’ buttons to turn your favorite music into a backing track, allowing you to play along. MIDI capability makes all lessons fun. Entertain yourself with a tune by playing along with the piano roll. Connect to other MIDI-enabled apps and external devices to individualize your lessons – throw away your old notions of practice, get creative and have fun.
