Vocafarre was a large VOCALOID event that Yamaha organized to promote the VOCALOID 3 software. It was held on the 15th - 16th Dec 2011 and was livestreamed via Nico Nico Douga. It was labelled "No.0". The event covered announcements for upcoming Vocaloid voicebanks and updates on Vocaloids. GUMI, Akikoloid-chan, VY1v3, Tone Rion and Aoki Lapis also appeared in concert together in Japan, dancing on stage. Though other concerts had been done for Vocaloid, this was the first official "3D" concert. Previously, all concerts had been done with 2D technology. This concert allowed Vocaloids to dance with real life dancers on stage for the first time.
