Scarlett 18i20 1st gen + PT 12.8.3

[literaldimwit]

Hey everyone, I have a 1st generation Focusrite Scarlett 18i20 that I am currently trying to get working in PT 12.8.3, on a used MacBook Pro with Sierra on it. I can't rely on any of the video tutorials I've seen; the one by Focusrite is only for 2nd gen devices, and the other one I saw... it said to do command+n when you saw the black program loading box, but every time I did that it crashed the program. There were a couple commenters on that video who said they had the same issue.

Mix Control is working perfectly fine as a standalone program; I had connection issues in the past but once I switched to a new USB cable they all went away.

I imagine there's something I need to do once I get a PT session started in order to record with it, but I feel completely inundated with all the options there are and I have no idea what does what.

What exactly do I need to do here?

Thanks, LD
