This should be a really obvious and simple task, but it’s not. I simply want to fade out the entire song by automating the master slider to slowly lower in volume until it fades to silence. YouTube video showed a person selecting read and write on master (stereo out) fader. On the video doing that created a line which you could click where you want the fade to start, and another click where you want it to end. But on my system I click on the master fader, select read and write and nothing happens… is there some sort of click your heels three times … or say mother may I? …what am I missing?
