Casio CTS400 Portable Keyboard Black

Wide range of voices and accompaniments

Create advanced compositions. As you're playing around with different creative ideas, you'll be able to experiment with any of the 600 different AiX tones. This vast selection of sounds, in Casio's remarkable AiX quality, will mean you find just the right one for whatever style you are after. Then, you can build up your music. There's plenty of backing to choose from with 200 rhythms and 200 one touch presets. Your keyboard can do a lot of the hard work for you if you choose, with 12 types of auto harmonise.

Features made for easy use

Keep your keyboard uncluttered with a backlit LCD screen and jog wheel. These quick and simple ways of navigating your keyboard's functions mean your instrument can have a clean and minimalist look. Plus, it's natural and intuitive to use as you can quickly switch between the different tones and see clearly which voice you're using at every moment, even if your environment is dark.

Advanced sound technology

Create an impressive sound. Casio's new AiX sound source has been redesigned from top to bottom to create the best keyboard sound that modern technology can produce. With high-performance DSP effects and master EQ, it produces sounds with greater clarity and expression than previously found in a portable keyboard. Added to this are the new Bass Reflex speakers, to deliver a powerful bass sound that will project your sound with strength. The sound itself is rich and surrounding, thanks to 48 note polyphony to let your notes ring out. Vary your sound with touch sensitive keys, which you can adapt with three different touch response levels. This will replicate the way that an acoustic piano's dynamics are altered by how strongly you press on the keys. Add expression to your performance.

New musical possibilities with connectivity

Using your smart devices with your keyboard has become a great addition for the modern musician. The CT-S400 keyboard caters for this with a USB microsocket in the back to easily connect to a smartphone, tablet, or PC. Also, with the option to connect a Bluetooth dongle (not included), your keyboard can become a Bluetooth speaker. Playing along with backing tracks you have composed has never been simpler. This would also make your keyboard a Bluetooth MIDI device, so you could easily connect to music learning apps like Chordana Play to support your with your musical progress.

Chordana Play app

Casio understands that technology plays a large part in education, and learning to play the piano is no exception! Now, when you use the WU-BT10 Bluetooth dongle (sold separately) you can connect your smartphone or tablet to your keyboard to unlock a wealth of educational features. You can choose between the 50 included songs on the Chordana Play app, or you can even add your own MIDI files. Chordana will automatically generate a music score from the file, and even detects chords, making it easier than ever to learn the piano.
