IT JUST HIT ME OUT OF NOWHERE!!!! Studio One does not have a native tapestop plugin neither is there a 3rd party one that allows the flexibility of a "Vari-fi" Protools tapestop plugin that you can apply to multiple files in a particular section at once. But Studio One DOES HAVE ARA and Maybe Presonus can make their own Native Tapestop effect using the ARA technology already in studio one which would allow for us to add the tape stop effect just as we would melodyne or Vocalign which would be non destructive and can be easily manipulated.
