Hello everyone.
I installed the drivers for my M-Audio Fast Track on my Windows desktop, and it worked just fine in Studio One 3.
But now I have installed the drivers for it on my Mac laptop, and Studio One is not detecting any Input channels for it.
It works just fine in other software, for example in Guitar Rig 5's standalone app. I can set it up and play guitar with it.

This is what the Input and Output sections in Studio One's audio settings look like:

I'm confused why it says "Built-in Output" in both sections.

Something is clearly wrong, and it's possibly because of the Fast Track's drivers being faulty.
But, since it works just fine in GR5 standalone I'm doubting that that really is the case.

Does anyone have any ideas?

Okay, I learned how to do it by making an Aggregated Audio Device by following this guide:

That was, of course, easy to do as soon as I understood that I HAD to do it.
Honestly, since Mac computers "just work", and you don't have to jump through all those "hoops" as you do with a Windows machine, I thought that something as simple as setting up an audio device wouldn't need any fiddling around in the operating system's settings.

I really don't like using iOS X, can you tell?

Anyway, I hope this can help someone!
