Reference 4 plugin routing: Logic

Setting up busses in Logic can be helpful or annoying, depending on what you are used to. When you create a Send on a Track, a corresponding AUX is immediately created. To set up several AUX tracks to receive from the same bus, you will need to duplicate the first AUX as many times as needed. Also, if you want to show the AUX track in the Main Window, you will need to select Create Tracks for Selected Channel Strips under the Options menu in the Mixer View.
