E.V.E.C.(Enhanced Voice Expression Control)

E.V.E.C. (Enhanced Voice Expression Control) is a newly developed function to expand the singing voice expressivity. E.V.E.C enables you to control detailed voice (vowels) expression, set release length and intensity of breath sounds, and also switch between different kinds of pronunciations. Get closer to your imagination of a dynamic VOCALOID singing voice than ever before!

Voice Color


[Stronger Sound] loud voice(vowel). Give tension to the voice.
[Softer Sound] Soft and tender voice(vowel). Useful when you want to take some intensity out of the voice.

Voice Release

Enables controlling the breath amount at the end of a word, e.g. to create a slow languorous breath at the end of a word, etc.

Add a long breath at the end of a word to create a languorous atmosphere at the end of a long vocal part.
Add a short breath at the end of a word, even in smaller vocal phrases

Pronunciation Extension Function (Stronger Pronunciation)

This function enables to switch to a stronger pronunciation when moving from consonant to vowel. You can give a stronger tension to the attack of words for every note. Also, this Stronger Pronunciation pairs beautifully with the Growl Function when you want to create a screaming voice, by turning on Stronger Pronunciation and adding a sufficient amount of Growl.
