Here are some videos I created for the Academy Juniors that you may find helpful if you have having difficulty figuring out your recording set-up. I didn't include instructions for those who may be using an audio interface with an external mic, but I am assuming that if you are, you already know how to do that. Just be sure to select the interface as your mic and set your levels through the interface.
