Your setup sounds overly complex and you have a lot more hardware involved than you need. You JUST need the Helix, you do not need the Scarlet or the Radial boxes.
Plug the Helix into your computer via USB.
In your DAW (I use Presonus Studion One v4.5, I would expect it to be the same in most DAW's), add a stereo recording track and use USB1 and USB2 as the stereo inputs to record the processed guitar sound from your Helix. That's actually optional, as you don't have to record the processed track if you don't want, but I always do. Add a second mono track using USB7 as the input - this records the unprocessed DI guitar track.
After recording, mute the processed track, add your processor of choice as an insert to the track (Helix Native, S-Gear, etc...) and set the tone you like.
Or send the DI track back to the Helix on USB 3/4 to reprocess it there with the hardware.
No other boxes required, just the Helix.
