Today I'd like to announce a new collaborative project featuring Hatsune Miku. Poland App featuring Hatsune Miku. Hatsune Miku exists in a software called Vocaloid. Vocaloid enables you to produce songs. a character named hatsune Miku sings the songs you create. A great feature is you can create songs as you like. I knew our talened Polish crew could work together and create GREAT, vocaloid.. songs.
