Using a Third Party Tuning Plug-in in Sunday Mix

You can definitely use a tuning plug-in with Sunday Mix like Waves Real Tune. You would want to put it directly under the compressor. The only things you’d want above a tuning plugin are EQ and Compression.

 You’ll also want to place a plug-in on every individual channel strip because each vocal will need to be processed apart from the others. You shouldn't place it on the Sub Mix channel strip.
