In the past, I’ve always thought that the main weakness of Vocaloid is that they sound horribly unnatural.
I thought they would be a passing fad, but when I finally heard an Electro Trance Vocaloid track that doesn’t sound robotic, I was blown away. As they keep topping Oricon charts, they have attracted a multitude of talented producers. Innovative technology has advanced rapidly enough for new Vocaloids, which are basically electronically generated vocals, to keep appearing in Japan’s E/DM scene. It sounds so natural, it scares me, but delights me at the same time.
