Casiotone CT-S1000V Keyboard

The CT-S1000V is an electronic keyboard for musicians and music creators who want to enjoy new kinds of keyboard expression and music production. The model is equipped with Vocal Synthesis, a newly developed onboard sound source technology that lets users play human, robot, and animal voices created by combining lyric data and vocal tones.

Vocal Synthesis is an original Casio sound source technology that employs a musical instrument to produce a singing voice. The human singing voice features complex variations in timbre depending on the lyrics and melody, and it is considered difficult to reproduce with conventional sound source technologies. While products pursuing the concept of replicating the sound of the singing voice in a keyboard format have been available for a while, they have not been easy to play for all users, since they have required special performance techniques and detailed adjustments. The new Casio technology solves all this by generating lyric phrases in simulated singing style, leveraging large volumes of singing voice samples, then combining them with vocalist data to create a smooth-flowing, human-style singing voice.

The CT-S1000V not only pronounces lyrics for each syllable each time a key is pressed but also automatically sings the user’s pre-set lyric phrases in the pitches and harmonies played on the keyboard. This way, there is no mismatch between the lyrics and what the user plays on the keys, and the user can perform freely without worrying about the lyrics. In addition, each syllable smoothly flows to the next, enabling intuitive musical expression and creation as if humming a melody.
