A brand-new function in the new software MEGURINE LUKA V4X allows you to vary the expression and control the strength of each word! The bilingual vocalist sings seamlessly between styles such as sweet breathy voice and growling voice.

The new version of MEGURINE LUKA V4X contains each 2 English and 2 Japanese databases which were elaborated for improving expressiveness. Each database was optimized for Cross Synthesis (voice morphing) and Growl functions which allow you to change the tension of the voice easily, and give also growl-like expressions to the voice. In Japanese, you can choose voice variations at each note in the song by the newly Crypton-developed function called E.V.E.C (Enhanced Voice Expression Control). Imagine the control of various expressions within one song: in a softer part of the voice whispers, whereas in the melodic in the melodic main part the vocalist pitches into a stronger high voice. Until now known limits of vocal expression are lifted with this new control! For your immediate music production, Crypton provides an all-in-one package including the new Piapro Studio vocal editor that lets you easily handle vocal functions such as E.V.E.C and pitch graphic control, and the music software Studio One which contains over 200 virtual instruments.
