Artificial Singing Synthesizer
The “Musical Isotope Project” focuses on artificial singing software born based on the singing voices of the virtual singers from KAMITSUBAKI STUDIO.
Originating and evolving from KAMITSUBAKI STUDIO’s theme of virtual singers that aims to “expand the possibilities of girls who love to sing,” this project not only positions itself as singing software capable of realistically reproducing human singing voices through the latest AI technology, but also as a creative partner that aids in the “expansion of creative possibilities.”
The future of musical isotopes derived from these girls exists infinitely, along with the potential of creators.
We believe that creations by creators, the so-called “UGC = User Generated Contents,” are what enriches this world.
We hope creators will utilize the “musical isotopes” as an inspiration for their creations, working hard on their artwork.
Our earnest wish at KAMITSUBAKI STUDIO is to foster an environment where numerous creators and expressions themselves are born and thrive.
