I'm trying to make an evil sounding song in Famitracker. So I decided to adding few spooky effect to the song. I made one, below you can find link. Any ideas how can I produce different kind of spooky effects like; scream, door creak, hysterical laugh, eerie ambiance, things like that.
Second, I'm using C Lydian (Augmented fourth) scale for the song. What other type of scales can be added to this?
