Harmonizing Plugin

Hey folks, brand new here, and to using plugins in a live performance in general! Currently using superrack performer with our Midas M32R. Playing multiple roles in this band, FOH, keyboardist and vocalist. Looking to add in another harmony very subtle. My questions would be:

1)What is a good plugin from the waves library to use live?
2)A little guidance on who’s rack to put it in (lead vocalist or one of the backing vocalists)
3)The best approach to change the key for the plugin for each song for each song it’s needed in.

Hopefully this all makes sense. I have zero clue on how to accomplish this or if it’s even possible for that matter :slight_smile:

Try Waves Harmony or WavesTune RT for a start.

As for the other SuperRack related questions hopefully someone else will be able to answer those as I have no experience using it.
