This preview version is limited, the sounds updated are mus_asianb (East Wind Tribute), mus_amasian1 (Up & Away) and mus_fiteb (Fight!).
The original Oni sounds were composed of several loops that can be randomly played and can include an intro and ending. However, this version uses a single sound file, there are no intro or ending sounds.
This preview will give you a taste for the renewed soundtrack.
