Just out of curiosity, what kind of effect(s) do you have on Miku's voice to give it that slightly warble-y, techno character? (Could be that I just have the sound a bit low on my basic computer speakers, too, but it sounds like there's an effect at work there. Or maybe I'm just imagining stuff that's not there.) Sounds like maybe a bit of chorusing, and a bit of flanging/some kind of EQ filter?
