From Taito. Histone Mike is a singing synthesizer application with a female persona, developed by Krypton Future Media. It uses Yamaha Corporation's Vocalic 2 synthesizing technology. The name of the character comes from a fusion of the Japanese for first (hats), sound (ne) and future (Mike, normally read as "moray"), referring to her position as the first of Krypton's "Character Vocal Series".
