This is a niche product but one of the best solutions for Audio, Video, and Lighting Playback in Theatre and the production industry. It transformed my workspace about 6 years ago and it's worth every cent. I've never seen pricing this low on this product. I've just upgraded my Lighting and Audio Licences (Version 3-4) as well as getting another full package.
The trial version allows audio playback on external devices but video is restricted to a single display - well worth having a play.
This software is bulletproof. Can highly recommend.
