Music in harmony—with the Casio CT-FS1BK in black!

The Casio CT-FS1BK Casiotone is an innovative, portable keyboard with 61 touch-sensitive keys, high-quality AiX sound generation and a fully monochrome black design. Building on the popular Casio CT-S1, the CT-FS1BK combines expressive sounds with an especially intuitive way to make music. The new Feel Sync feature lets you play along with selected songs right away—even without prior musical experience. With 61 high-quality tones, 64-note polyphony and a powerful stereo speaker system with Horizontal Bass Reflex, this digital keyboard offers a versatile sound experience. A special highlight is the included Casio WU-BT10 Bluetooth adapter, which lets you transmit audio and MIDI data wirelessly. The consistently black all-black design, including matching black keys, also makes the CT-FS1BK a stylish musical instrument for modern living spaces.

Feel Sync—intuitive music-making, even without prior experience

The innovative Feel Sync feature gives you an especially easy way to start making music with others. First, select a song from the built-in SONG SELECT collection. Feel Sync’s intelligent technology analyzes the musical harmonies and other characteristics of the selected piece. As you play the keys, the algorithm takes into account your timing, dynamics and the number of notes you play. The tones produced are automatically adapted to the music playing. This lets you focus on the rhythm, musical expression and your own personal style without constantly having to watch for the correct notes. Even if you’ve never played a keyboard before, you can become part of a musical performance right away. The feature also offers experienced musicians an interesting way to improvise spontaneously and explore new musical ideas.

61 touch-sensitive keys and high-quality AiX sound generation

The Casio CT-FS1BK has 61 touch-sensitive keys with three adjustable sensitivity levels. The keyboard responds to different playing strengths, allowing expressive performances with natural variations in volume. The powerful AiX Sound Source offers 61 carefully developed tones, including 10 Advanced Tones and 12 distinctive Casio Classic Tones. From authentic piano and electric piano sounds to organs and a wide range of other instrument tones, you have a varied palette of sounds at your fingertips. Maximum 64-note polyphony ensures that even complex chords and musical arrangements are reproduced with clarity. The Layer function also lets you combine two tones to create especially expressive sounds.

Bluetooth MIDI and audio with the included Casio WU-BT10

The original Casio WU-BT10 Wireless MIDI & Audio Adapter is included with the Casio CT-FS1BK. Unlike with the CT-S1, you don’t need to purchase this Bluetooth adapter separately. Once plugged into the USB TO DEVICE port, the WU-BT10 enables a wireless connection to compatible smartphones, tablets and other suitable devices. With Bluetooth audio, you can play your favorite songs and backing tracks directly through the keyboard’s speaker system and play along. Bluetooth MIDI also enables wireless transmission of MIDI data to connect with compatible music apps and MIDI applications. This gives you a modern, flexible connection between your Casio keyboard and your digital music setup, with no additional MIDI cables required.

Expressive stereo sound with Horizontal Bass Reflex

The built-in speaker system delivers surprisingly full, spacious sound. Two oval speakers, each with 13 x 6 cm diaphragms, are powered by a stereo amplifier rated at 2 x 2.5 watts. Horizontal Bass Reflex technology supports powerful, balanced reproduction of low frequencies. Piano sounds and dynamic instrument tones in particular benefit from a rich tonal foundation. The built-in Surround function can further expand the sense of space. Volume-Sync EQ also helps maintain a balanced tonal character at different volume settings. This makes the CT-FS1BK suitable both for focused practice and relaxed musical moments with family and friends.

A wide range of effects and practical music functions

In addition to AiX sound generation, the Casio CT-FS1BK offers many ways to shape your sound. These include 24 reverb types, chorus, delay and DSP effects, as well as a master equalizer with 10 presets. The Layer function lets you combine different instrument tones. A built-in metronome helps you practice rhythm, while the transpose function and octave shift add musical flexibility. You can record and play back your own performance with the MIDI recorder. The Tone Memory function lets you conveniently recall your preferred tone settings. This Casiotone keyboard offers versatile features for beginners, hobbyists and creative musicians.

Monochrome all-black design for modern living spaces

With its consistently monochrome appearance, the Casio CT-FS1BK stands out from traditional keyboards. The body, controls and keys are all finished in black. Instead of the traditional black-and-white keyboard layout, this instrument features an exceptionally minimalist all-black look. This pared-back design gives the Casiotone keyboard an elegant, modern character that blends harmoniously with a wide range of interiors. Whether on a keyboard stand in the living room, in a music room or in a creative home studio, the CT-FS1BK stands out both as a musical instrument and as a stylish design object.

Flexible connections and mobile power options

The USB TO HOST port lets you connect the keyboard to a compatible computer for MIDI applications. The AUDIO IN input allows wired playback from external audio sources. Use the headphone/audio output to practice quietly or connect the instrument to suitable audio equipment. A separate pedal input allows you to use a compatible sustain pedal. Powered by a suitable 9.5 V power adapter or six AA batteries, the Casio CT-FS1BK is also suitable for mobile use. Measuring (W x D x H): 93 x 25.8 x 8.3 cm and weighing 4.6 kg, the instrument remains compact and easy to transport.

The modern keyboard for making music together

The Casio CT-FS1BK combines high-quality keyboard technology with a new, especially accessible musical experience. The Feel Sync feature invites you to explore music intuitively, while the touch-sensitive keyboard and powerful AiX sound generation also offer more advanced options for musical expression. The included WU-BT10 Bluetooth adapter makes it easy to play along with your favorite music and use modern MIDI applications. Together with the powerful speaker system and distinctive monochrome design, it makes for a versatile home keyboard that convincingly combines technical quality, creative freedom and stylish design.
