A Virtual Singer created for Mac Computers, since Vocaloid2 doesn't run on the Mac. The Seiyuu Inoue Kikuko provided the voice samples for Macne COCO. In June 2010, Coco's twin partner Macne Coco_(Kuro) was released.
Macne voicebanks can be transferred to the UTAU program. But Coco herself is not an UTAUloid.
