On the music side, there are new loop composition features: Dynamic Transport mode allows playback to operate independently of the current selection and the Loop Trim tool turns audio or MIDI regions into loops. I especially like the new metronome pull down: just pull it down and a click track with an already instantiated metronome plug-in pops up in the mixer already to play at the session tempo.

Since Digidesign recently bought the Sibelius notation software company, Pro Tools 7.3 now outputs, with the "Send To Sibelius" menu command, for instant notation of MIDI compositions or individual tracks to Sibelius for printer copies of arrangements or instrumental parts--look for integrated notation in future Pro Tools software. User customization and speed-enhancing features start with the new Window Configurations feature for storing and recalling up to 99 window layouts. Memory location, Zoom Toggle preferences, and track heights are now user-customizable. To keep the music pumping, users can make many changes to their mixing configurations without manually stopping and restarting playback, and a new drag-and-drop plug-in settings function allows for instant plug-in opening or settings recall. For post professionals working with Pro Tools LE 7.3 software, the DV Toolkit™ 2 option adds new QuickTime® video editing and export features, as well as integrated multi-channel field audio matching.
