KAGAMINE RIN/LEN V4X: Vocal Synth Plugin by Crypton Future Media

The Rin and Len banks come in several variants. Rin has a Japanese POWER bank for strong, slightly furious tones, a WARM bank for gentle female vocals, and a SWEET bank with whispery breath effects. Len has a POWER bank for frank, powerful inflections, a COLD bank for calm, soft young male vocals, and a SERIOUS bank with a lonely whispered quality. English databases for both characters are also included, with natural pronunciation.

Each bank lists a suggested tempo range and a recommended vocal range, so you can match a voice to the register and pace of your melody.

E.V.E.C. (Enhanced Voice Expression Control) lets you shape vowel detail, set the release length and intensity of breath sounds, and switch between pronunciation types. Strong and Soft Pronunciation change the attack when a sound moves from consonant to vowel. Strong Pronunciation is designed to pair with the Growl function for screaming voices, while Soft Pronunciation gives a breathy, quiet tone.

Voice Color controls overall vowel tone, and the Voice Release options add either a long or a short breath at the end of a word. Gender Factor, Cross Synthesis and Growl are available inside Piapro Studio.

The plugin suits producers who need sung vocal parts in J-pop, electronic and other styles that use synthesized voices. Its tempo ranges cover slow to fast material, and the breath and growl controls give room for both soft and intense phrasing. Because Piapro Studio runs as a VSTi inside common DAWs, the vocal editing can stay in your main session.
