About Tonio

Vocaloid 2 is a singing vocal synthesizer and the successor to the Vocaloid voice synthesizer application by Yamaha. Unlike the first engine, Vocaloid 2 based its output on vocal samples, rather than voice analysis. The synthesis engine and the user interface were completely revamped, with Japanese Vocaloids possessing a Japanese interface, as opposed to the previous version, which used English for both versions. It is noteworthy for introducing the popular character Hatsune Miku. It was succeeded by Vocaloid 3. This version was not backward compatible with the original Vocaloid engine. Its first voice bank, Sweet Ann, was released in 2007. New features included note auditioning, transparent control track, toggling between playback and rendering, and expression control.
