BUMP OF CHICKEN and Hatsune Miku collaborate in a duet song, RAY, making it the first ever music video featuring Miku without any CG editing involved– that is to say, it was filmed in real time.
The Hatsune Miku module used here, named “14 Model” was created and manipulated entirely by Crypton engineers. You can watch an eight minute documentary on how this video was created here.
Her voice manipulation was done by kz from livetune. This song is available on the iTunes store!
