Tokyo-based electronic musician has worked with a handful of vocalists during his short stint as a producer. However, many of them haven¡¯t been human.

His go-to voice belongs to Sekka Yufu, who boasts a light delivery that fits with ¡®s slowly unwinding swirl of synthesizers. She¡¯s a computer-generated voice powered by software called Utau, a free-to-download application resembling the popular singing voice synthesizer program Vocaloid.

¡°Yufu isn¡¯t like Hatsune Miku,¡± says, comparing her to Vocaloid¡¯s main megastar. ¡°She¡¯s kind of a minor character. She has a whispery voice and nothing like that exists in any of the Vocaloid voice banks. I thought it was very cute.¡±
