Casio Intros Casiotone CT-S1000V Vocal Synthesis Keyboard, Casiotone CT-S500 Portable Keyboard

Casio has announced the portable Casiotone CT-S500 keyboard and its big brother, the CT-S1000V, a vocal synthesis keyboard that can turn any text, such as song lyrics, into musical phrases that the keyboard can “sing”, in full harmony, based on the notes that you play.


Casio says that no keyboard instrument has ever before been able to speak and sing with this degree of ease and musicality.


The CT-S1000V is a fully-featured ‘standard’ home keyboard, offering 800 AiX-powered sounds and 64 voices of polyphony. On top of this you get 243 built-in rhythms, 150 arpeggiator patterns, effects, a metronome, a built-in recorder and basic sampling functionality.


The 61-note keyboard is velocity-sensitive, and there are three assignable controllers. Up top you’ll find stereo speakers, while connectivity comprises two pedal inputs, a mini-jack audio input, 1/4-inch stereo line outputs, and a mini-jack headphones output.


There is also a USB-A port that can accommodate the supplied Bluetooth audio/MIDI dongle, and a second USB-B port for connection to your mobile device when you’re using the Lyric Creator app.


The CT-S1000V comes with a power supply and can also be powered for up to three hours from six AA batteries.


Phrases can be played all at once, according to a set rhythm when keys are pressed, or one syllable at a time as new notes are played – with or without legato. They can also be sequenced together to play complete songs.
