A quick question for you touring guys- What is the correct way to implement Auto-tune, as a vocal effect, in a live situation? Presuming it's not a track and being used as pitch quantization rather than correction. I've never been asked to use one other than the occasional vocal pedal. Does it happen from stage? Does the effect get fed into the monitoring system? I'm sure there are many right answers. Just curious how you guys do it. Thanks!
