Crypton Future Media is providing JapanFiles with a growing number of album releases based on their Vocaloid software and famous characters Hatsune Miku, Kagamine Rin/Len, and Megurine Luka.
Hatsune Miku is the first installment in the Vocaloid2 Character Vocal Series created by Crypton Future Media and the most popular and well-known Vocaloid, released on August 31, 2007. The name of the title and the character of the software was chosen by combining Hatsu (First), Ne (Sound), and Miku (Future). The data for the voice was created by actually sampling the voice of Saki Fujita, a Japanese voice actress.
Released on December 27, 2007, Kagamine Rin/Len is the second installment of the Vocaloid Character Vocal Series, male voice (Len) and female voice (Rin). Their family name was chosen by combining Kagami (Mirror), Ne (Sound), with the first syllables of their given names, puns on "Left" and "Right". Despite popular depictions as fraternal twins, they are not actually brother and sister, but are reflections of a mirror. According to Crypton's official blog, the package includes two voice banks: one for Rin and another for Len, both provided by Asami Shimoda.
Released on January 30th, 2009, Megurine Luka is the third Vocaloid2 in Crypton's character series. Her surname combines Meguri (Circulate) and Ne (Sound), while the name Luka invokes the homonymous Japanese words of "nagare" (flowing) and "ka" (song) or "kaori" (scent). Yu Asakawa provided the "moody yet husky female voice" for the "cool, somewhat mysterious" character.
Developed by Crypton Future Media, the Character Vocal Series is a computer music program that synthesizes singing in Japanese. It utilizes Yamaha's Vocaloid2 technology with specially recorded vocals of voice actors. To create a song, the user must input the melody and lyrics. A piano roll type interface is used to input the melody and the lyrics can be entered on each note. The software can change the stress of the pronunciations, add effects such as vibrato, or change the dynamics and tone of the voice.
Each Japanese Vocaloid is given an anime-type character with specifications on age, height, weight, and musical forte (as in the type of music, range and tempo). The characters of the first three installments of the series are created by illustrator Kei.
