Does anyone know what applications LiveCut, Supatrigga or Bufferoverride are compatibale with? Tried to install the dmg files to my Mac for use in pro tools to no avail...then tried the pc files for adobe audition with same results. Any info would be much appreciated...

You should just be able to go to those manufacturers web sites and find support on which host app they are compatible with, as well as what versions are comparable with your OS. Also will probably tell you what format those plugs are and from there you just need to find a host that accepts the plug format of the plugs you have i.e. VST/AU/RTAS/AAX/AAX32/AAX64...so on and so forth.
Hope this helps, best of luck.
