You may be wondering why my songs with Vocaloid2 (Hatsune Miku, Kagamine Rin/Len, Megurine Luka) are not tagged so, with few exceptions.
Here is why. Because I have not obtained license from Crypton Future Media (publisher of Character Vocal series of Vocaloid2) to use character likeness.
According to Crypton Future Media’s license they require additional license for the following form of use.
(1) Use in Commercial Karaoke
Use of generated audio in commercial karaoke software, karaoke hardware, karaoke system using the Internet, other commercial karaoke product, and karaoke service (including online, offline, and other form)
(2) Use in Commercial Telephone / Mobile Phone Ringtones
When generated audio is used commercially for telephone (including mobile) and equipments for telephone (here after “telephones”) ringtones. However, this agreements covers ringtones, and warning tones including generated audio, but mixed with other musical instruments and in case of use within musical work, in which case do not require additional license.
(3) Use in Videos
Use as if characters in video work (including animation) is singing and performing with generated audio.
(4) Product Display
Title of the product (“Hatsune Miku,” “VOCALOID,” “Virtual Artist,” or related display (hereafter “contractual display”) is credited and prominently displayed to end user on the product, package, promotional material, and/or staff credit on video works as singer, artist, musical instruments, which utilizies generated audio, and used for commercial trade and performance.
Although most of my work are available free of charge, but at same time most of my works are published by a profit corporation, I cannot use their mark, unless I obtain license from them. That’s why you don’t see Vocaloid2 names on my work.
In same count, there are people who are actually selling digital album on the net with Vocaloid2 mark and names. I’m not sure if they are properly licensed. Although I’m not really sure Crypton Future Media’s enforcing those very strongly.
