A Vocalist You Can Play, an Instrument That Changes the Concept of Playing


A vocalist that sings at the touch of a key . . . The CT-S1000V is an instrument that redefines the concept of a keyboard and how it’s played. At its core is Casio’s new Vocal Synthesis technology, which lets you go beyond conventional playing, opening up new creative possibilities and freedom of musical expression. Capture that moment of inspiration in real time and enjoy a unique musical experience.



Vocal Synthesis – Technology That Allows an Instrument to Find Its Voice


Hear your own lyrics sung as you play the melody on the keyboard. The CT-S1000V is a completely new kind of electronic musical instrument. Using Casio’s unique Vocal Synthesis sound source technology, it takes lyrics from your smart device and—using one of the range of built-in vocal tones—lets you play the vocal line using the keyboard. The CT-S1000V is not a conventional synthesizer or keyboard, nor is it a simple production device. It opens up possibilities for unprecedented freedom and creativity in vocal performances.

A Keyboard Instrument That Can Sing as Intuitively as You Can Hum


The CT-S1000V lets you bring vocals to your performance as intuitively as if you were humming them. As you play the keyboard, the words of the lyrics are sung in sequence to create a vocal line. Not limited to a specific melody for your vocal, you’re free to get inspired as you experiment with different musical ideas. You can also change the voice tone, add and tweak effects in real time while playing, and generally get creative with your performance. More than just another sound source, the CT-S1000V is truly a musical instrument with as yet undiscovered musical possibilities.


Develop Musical Ideas with the Instrument’s Vocals


At the heart of the CT-S1000V is Casio’s unique Vocal Synthesis technology. Smoothly sung vocal lines can be produced from any lyrics input with no further special settings required. You can even play harmonies to recreate the sound of a choral group. Experience a completely new kind of musical performance not possible with conventional sound sources. Two modes are available: Phrase Mode and Note Mode. Phrase mode is recommended for experimentation and improvisation when developing ideas. The lyrics are sung in order as you play for a very natural playing experience. In Note mode, the lyrics advance one syllable at a time as you press keys on the keyboard.

Start Creating Vocal Tracks Instantly Without Special Equipment or Skills


Vocal Synthesis produces a singing voice through a combination of lyrics and voice tone. The CT-S1000V comes with 100 pre-built lyrics to get you started, but the real fun happens when you create and save your own lyrics on the dedicated app. There are 22 preset vocal tones (vocalists), each with its own distinctive character. Each vocalist can be further manipulated with front panel controls for age, gender, vibrato and more. A range of other settings are also available to personalize your vocals. Parameters such as attack time, modulation, effects, an arpeggiator, and a retrigger function that produces a rapid series of keystrokes when a key is held down. Using the Lyric Creator app, you can input your own lyrics, provide detailed pronunciation information (for English and Japanese), and create sequences that can be strung together to form songs. You can even create your very own vocalist from any audio data.

Instrument Designed for Realism


Vocal Synthesis has been made possible by Casio’s AiX Sound Source, which brings together the best of Casio’s advanced technologies. And while Vocal Synthesis makes possible the realistic vocal tones of the CT-S1000V, you’ll also find a wide variety of other tones with a special focus on expressivity. In total, there are 900 tones to explore, including a collection of ADVANCED TONES, which push the AiX Sound Source to new limits of expression, and the CASIO CLASSIC TONES, which reference the classic sounds of Casio’s lineage of synthesizer keyboards.


A Wide Range of Effects for Total Freedom of Expression


Naturally, the CT-S1000V comes with a wide range of built-in effects—100 in total including compressor, phaser, distortion and wah. Chains of four different effects can be applied to any tone, and thanks to Casio’s Active DSP you can assign effect parameters to the front panel knobs for dynamic, real-time tweaking. Additionally, there are system-wide chorus, delay and reverb effects. The flexibility of the effects is also noteworthy—you can assign independent effect chains to each tone used in a Layer or Split, or the tones used for melody and accompaniment parts. What’s more, tones can be switched seamlessly as the effect tail from the previous tone plays out naturally without being abruptly cut off. With this kind of attention to detail, the CT-S1000V is truly a powerhouse of expression.

Complete with a Sound That’s Bigger Than It Looks


The CT-S1000V has two built-in speakers that pack a surprising punch thanks to Casio’s unique Horizontal Bass-Reflex System, which is capable of producing powerful low-frequency sound. A surround function adds width and depth to the sound, while the Volume Sync Equalizer ensures that the tonal balance of the sound is maintained when you adjust the volume, providing added depth and weight even when playing at low volume. All in all, the CT-S1000V delivers sound that completely belies its compact dimensions.

Sample Your Own Sounds to Develop Your Own Style


The CT-S1000V’s sampling capability means you can import your own sounds from a smart device to use as a unique Sampling Melody Tone or Sampling Drum Tones. When imported as a Melody Tone, the imported audio can be played as pitched notes, while audio imported as Drum Tones can be set to replace individual hits in a drum set. Maximum sample time is about 10 seconds for the Melody Tone and about three seconds for each Drum Tone. Experiment with different kinds of sounds, such as your own voice or environmental backgrounds, then add effects and control parameters in real time with the Active DSP function. Discover your own musical originality.

Broaden the Possibilities with the Connectivity to Use the Equipment You Want


The CT-S1000V plays nicely with your other gear, too, thanks to its comprehensive lineup of external connections. The standard line out jacks are ideal for hooking up to a keyboard amplifier, mixer or other equipment for recording or live performances, and the built-in speakers can be muted if required. Connection to other MIDI-compatible equipment is fully supported, enabling the CT-S1000V to be used as a MIDI-controlled sound source or as a MIDI controller. You can even use the CT-S1000V as a Bluetooth® speaker for your smart device using the Bluetooth® audio function. Using the CT-S1000V together with the dedicated app expands the possibilities further still with features like melody/accompaniment cancelation, pitch adjustment and tempo adjustment—perfect for playing along with your favorite songs or honing your play-by-ear skills.

The Freedom to Enjoy Music Any Way You Like, No Matter Where You Are


The compact size of the CT-S1000V makes it super portable, and its built-in speakers mean you can play it anywhere without external amplification. The console panel has been designed for simplicity so that controls for volume, tone, rhythm, effects and Vocal Synthesis are intuitive and easy to adjust in real time while playing. Five user-assignable buttons under the LCD screen can also be set up to suit the way you use the instrument. The whole package has been designed for musicians to create their own music and develop their own performance style however and wherever they like.
