You can use multiple audio interfaces simultaneously inside Logic Pro. First, you need to create an aggregate device in the Audio MIDI Setup utility. Logic pro composition. Creating an aggregate device allows you to join multiple audio interfaces into a single device, thus increasing the number of inputs and outputs available in your project. To create an aggregate. Finding the best interface for Logic Pro X is not too hard, but some devices work better than others. We have selected three audio interface models that we think are the best you can use with Logic Pro X. You see some familiar names on this list, and some that are known much outside the Apple community.
I don't know what any of that external equipment is (some people on this Forum will do, but most will not), however, leaving that aside, it looks as if the question you want answered is:
+How do you get more Outputs from Logic than just the stereo Master Outputs?+
The answer is that it will depend on the driver for your interface. Assuming your interface supports multiple outputs from Logic, then you will be able to set them up in
+Applications > Utilities > Audio MIDI Setup+
Once you've done this, you should be able to choose any of those Outputs for each Output object in the Environment. If you need help creating new Output objects, LMK & I can take you through it; but probably that's already enough info to get you going…
