Logic Pro can automate loops for you. Learn more mixing techniques in Logic Pro 8 software in this free music production video from a professional audio engineer.
Now, it's pretty easy to automate your loops. And on every loop, all you got to do is press the A button with your caps lock off and you're able to open up a whole automation screen set that lets you change the volume and write different changes within your song that will automatically work as a song plays. Now, what we can do is we can type "A" and that's going to open up these little windows. Now, when you open that up, the first thing that pops up is the "Volume". What we're going to do, we're going go to "Read". And what we're going to is do is we're going to change certain things within here. Maybe just change -- add a zero there, add a zero there, bring it down. Get another zero, bring it back up to right here to where the loop starts back up again. And listen to our track. (Music plays). So, you see, that we just drew in a volume change and as the song plays, once it gets to that point, it's going to start fading down and then once it goes back to the next loop, it goes right back up to zero.
