Ive Heard the term be thrown around before, what i wish to do is use rewire to make vocaloid3 an audio device in ableton

what i currently did for this was make the voice in Vocaloid3, export it, import to ableton on top of my track, and see if it worked. I know its possible to use ReWire, but i have no idea how. thanks.
