Hatsune Miku
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. The name of "Hatsune Miku" was conceived soon after the Vocaloid 2 announcements, when an English and Japanese vocal were developed for the character. The intended design was delayed and later used for Megurine Luka instead. Miku was intended to be the first of a series of Vocaloids called the ""Character Vocal Series"", which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.

The software itself comes with a small number of models of well-known Vocaloids and an invisible grid, to which particle effects can be attached to in MME, a stage, some accessories, and two samples of what MMD can do, in the form of .pmm files; the file type that MMD projects are saved as. The software was originally only released in Japanese; however an English version was released at a later date. Videos using the software are regularly seen on sites such as Nico Nico Douga and YouTube and are popular among Vocaloid fans and users alike. A magazine which hands out exclusive models with every issue was also produced owing to this popularity. Some models for Vocaloid may also be used for Vocaloid music, going on to be used by studios working with the Vocaloid software.
