Ok so my band has 2 vocalists with very different techniques to each other. We have plans for a sophisticated all in one live rack case built around an interface. Probably the 18i20. Anyhow, i wonder if Gain reduction (seperate instance on both vocal) works well live? Even if subtle? Could also automate it to do different degrees of compression depending on the part of the song. Anyone had any experience using GR live? Seems a better direction than a physical vocal fx pedal.
