How do you add a sound file with rehearsed timings that will play throughout the whole presentation? What I did was added a sound file. Then I played it and rehearsed the times for each frame so when that particular part was finished, it faded slowly into the next frame and so on. But when I do that, the song will play automatically but when the frame is done, it doesnt go to the next and the song keeps playing. Does this make sense?
