We use VocalSynth2 from iZotope which is amazing. We use it on basically every song we have got placed with big bilboard artists and are palyed daily on the radio etc
Been out for years and is very stable in Pro Tools 2021.6 but we been using it sknce it came out. Can’t remember what version pf PT was the one out when we bought the Vocalsynth 1 but it sure works with 11/12 atleast and up..
