To schedule a long audio file that spans multiple hours in PlayIt Live, first add your file as a track via Manage > Tracks. Then create two clock types: a "Show Start" clock containing a Hard Fixed Time Marker at 00:00, your usual top-of-hour elements, and your long audio file; and an "Empty Hour" clock containing a single 60-minute Break Note. Schedule the "Show Start" clock for your first hour, the "Empty Hour" clock for subsequent hours the audio file will play through, and ensure your next regular clock after the show ends begins with a Fixed Time Marker. This setup allows your long audio file to play completely across multiple hours without unwanted content being scheduled, and the Fixed Time Marker in your post-show clock will automatically clear any remaining Break Notes. This method requires no manual intervention once set up properly.
