Prism can run as an ARA and traditional plugin
Prism supports VST3 and AU plugin formats. We are currently working on an AAX plugin for Pro Tools.
Prism works in ARA mode in the following DAWs: Reaper, Studio One, Cubase, Logic Pro (Intel or Rosetta), and Cakewalk Sonar.
Prism should work fine in all DAWs as a traditional plugin (non-ARA mode).
