初音ミク
Hatsune Miku received an update for Yamaha's Vocaloid 4 engine under the name of "Hatsune Miku V4x". It makes use of the new EVEC system for Piapro Studio, a VSTi plugin used as an alternative to the traditional Vocaloid Editor. EVEC consists of recorded vowels. Along with the consonant, a different vocal tone can be achieved. Two vocal tones are included in the EVEC system: "Power" and "Soft". Along with the new EVEC system, phoneme errors found in Miku's V2 and V3 voicebanks would be fixed allowing for easier manipulation of her voice. , Hatsune Miku V4X/V4 English was released.
