"Digidesign's flagship software product is Pro Tools, which comes in three variations: Pro Tools|HD, Pro Tools LE, and Pro Tools M-Powered. Pro Tools|HD requires a Digidesign TDM system and interface, and is intended for professional recording studios. Pro Tools LE is a complete package intended for home users and some post-production facilities. The package includes the Pro Tools LE software and hardware such as the M-Box 2 or Digi 003. Pro Tools M-Powered is simply the Pro Tools application adapted to run on M-Audio hardware, and is generally comparable in power to LE systems."
