Question Why are VST and AU formats not supported on LC2n and LC6n  Answer There are two elements to the LCn:
  1. A plug-in for Pro Tools 
  2. A stand-alone app for PC and MAC
So, why is there no plug-in for other apps than Pro Tools  The plug-in needs to pass thru the audio two times (multi-pass), one for measuring, one for correcting the audio. Pro Tools is the only DAW that supports multi-pass, offline rendering, and thats why LCn only supports Pro Tools.  For users of other DAWs, the stand-alone application is the right choice.
