I used "MikuMikuDance(MMD)"n_n
Music made it partially drive by the pronunciation sign etc.
in "David Bowie's Scary Monsters" It was "luka megurine (English)" and sing.
The accompaniment also has the part where the MIDI driving and
the sampling material were basically pasted
(Use it for music by about seven tracks).
It raises it to "BPM140" as it makes by "BPM135"
and it is a time stretch and the pitch conversion doesn't exist.
