Casio CT-FS1 White

The CT-FS1: the CASIOTONE spirit in a monochrome design

As the successor to the CASIOTONE CT-S1, the CASIO CT-FS1 retains an approach focused on the joy of playing: accessible controls, a portable format and a varied sound palette. This white CT-FS1WE version stands out with its monochrome styling, also available in Black under the CT-FS1BK reference.

With its clean lines and acoustic fabric integrated into the front panel, this keyboard naturally fits into any interior. Its 4.5 kg weight without batteries and its 258 mm depth also make it easy to move from room to room or take on the go. The addition of Feel Sync expands its approach: you can work on your playing, but also simply experiment and share a musical moment.

Keyboard design

The CT-FS1 features 61 velocity-sensitive keys. Three sensitivity levels allow you to adapt the keyboard's response to your playing style; this response can also be disabled. Playing intensity thus becomes a genuine means of expression, allowing you to add nuance to a melody or give an accompaniment greater depth.

The monochrome keys contribute to the instrument's visual identity and the Feel Sync experience. The control layout prioritizes direct access to essential functions, without adding unnecessary steps when you simply want to sit down and play.

Sound quality

The AiX sound source reproduces the characteristics of acoustic, electric and electronic instruments. The 61 sounds include a stereo acoustic piano, electric pianos and strings: a selection that lets you move from piano practice to more enveloping textures. The 64-note polyphony is particularly useful for layering sounds.

Two 13 x 6 cm speakers, powered by 2.5 W + 2.5 W amplification, make up the Horizontal Bass Reflex stereo system. The Volume Sync EQ adjusts the tonal balance to preserve bass presence and treble clarity at low volume. The headphone output lets you continue practicing discreetly.

Built-in effects

To give the sounds space and character, the CT-FS1 offers 24 reverbs, as well as chorus, delay and DSP processing with presets associated with the sounds. A 10-setting master equalizer, a surround effect and Volume Sync EQ further expand the adjustment possibilities. Headphone mode enhances personal listening.

Educational functions

The adjustable metronome from 20 to 255 helps stabilize the tempo and structure practice sessions. Layer mode combines two sounds to enrich a part, while transposition and octave shifting let you adapt the register. The free CASIO MUSIC SPACE app makes it easy to change sounds from a connected device.

Feel Sync offers another way to approach playing: start a song recorded on your device with the dedicated app, then play along according to your feel and the rhythm. This function uses local WAV, AIFF or MP3 files; streaming services, including subscription-based services, are not supported.

Advanced functions

• Bluetooth Audio and MIDI with the included WU-BT10: stream music through the keyboard's speakers and exchange MIDI data with a compatible device.
• MIDI over USB with 16-channel multitimbral reception for integrating the keyboard into a connected musical setup.
• Extended musical settings: adjustable reference tuning, equal temperament and 16 variations, transposition and sound-layer balance.
• Versatile connectivity: audio input, headphone output usable as an audio output and a sustain pedal jack.
