Using Aux Inputs for FX

OK, so today we're going to learn about how you can use the Aux Sends in Pro Tools to put an effect on a bunch of tracks at once.

First of all, what the #*!& is an Aux Send?

An Aux Send is a part of a mixing board that lets you take the signal from one track and direct it somewhere else.

Why would you want to do that?

One big reason is to have a multiple tracks going to the same FX processor.

Why would you want to do that?

• versatility - isn't it more useful to have an effect be accessible to every track rather than just one track? Also, you can get really creative by sending sounds to different places and doing different things in the mix.
  
• simplicity - instead of putting an reverb on every track, you can just have one reverb and send whatever you want to it
• less processing power - why make your computer do a bunch of extra work if you don't have to
• gives your mix a more consistent sound.
  

So, where do you find the Aux section in Pro Tools? In the Mix Window, it is the light grey section under the Inserts.
When you click on one of the double arrows, you will be asked to choose either interface or bus. What is the difference?

Interface refers to something outside of the computer - you are talking about running something into or out of Pro Tools.

Bus refers to directing a signal to somewhere else inside Pro Tools, like another track.

Actually, you can create a special type of track in Pro Tools that is meant for being used with the Aux Sends. It is called an Aux Input and you can create it the same way you would create an audio track: Track>New Track

From there you just change the type of track from audio to Aux Input.
To setup a basic Aux track with a reverb on it, just do the following:
