I have always been the Sound Tech for all of the Performances at the High School. As people are coming in we are going to have Sinatra music playing...and every 10 min I want an automated to remind people to turn off their cell phones. Scenario 1: OK...I need a program (if it even exists) to: Have music playing Fade the music Play a the message Fade music back in Kinda like phone systems when you call in to a company? Scenario 2: Have a program that I can use to fade and mix the music and message ahead of time then Burn it to a CD then just play it the nights of the performance. I really would like it if it was a free program if at all possible. Thanks in Advance!
