Help Using Rocksmith 2014 as a [Professional] Amp Simulator

[vandorb12]

Yes, I know there are better programs out there, but when you have dozens upon dozens of amps, cabs, and effects for less than $10USD (when sales happen), you start to wonder about these things and by gosh darn golly these things need to be tried at least once when you're young.

Right now I feel like I'm a little bit over my head when it comes to getting a DI track I made and getting it to play in Rocksmith 2014, and back into my DAW. I'm overthinking things, and I need some like-minded people to help me clear my thoughts and help me think outside the box.

Here's what I have on hand:
Rocksmith 2014 - Remastered
Rocksmith ASIO mod (just in case)
Rocksmith cable
Reaper 6
Focusrite Saffire Pro40
Behringer Ultra-DI Pro
DIYRE L2A Passive Reamplifier
A bunch of 1/4" and XLR cables
Realtek High Definition Audio (PC)
ASIO4ALL

I would like to limit the number of times I have to AD/DA the signal to keep it as free from muck as possible because my room is "electrically noisy".

So far my plan is to use Line 3 out of the Focusrite to send my DI track into the L2A, pass it through the Rocksmith cable into Rocksmith 2014, and then use some sort of loopback on the Focusrite to record the now amp'd signal. Getting the signal back into the DAW is my main roadblock. I personally have never used the loopback on my interface, I've read up on it but I might be too thickheaded to understand how to properly route it.

I was thinking about using OBS to record playback, but the recorded audio is lossy and I have to deal with extracting the audio from a video file after the fact.

I appreciate the support and guidance! Keep rocking!
