Doubling is one of the best techniques for fattening up a lead vocal or giving it extra depth. And Duo is the easiest way to enhance vocals with a realistic doubled vocal part—automatically generated from your existing vocal. In addition to programmable variation in pitch, timing and vibrato depth, Duo includes adjustable vocal timbre modeling, so you can create a doubled part that sounds like the same person as the lead vocalist—or like someone else entirely. It also gives you independent control of the level and pan of the original and doubled voices, so you can craft the perfect stereo mix. Just put Duo on your vocal track, and adjust the variation parameters and output controls to create exactly the doubling effect you’re looking for Instant doubling.
