There will be four separate setups you will need to take care of:

• Creating a folder on your local machine for your session.
• Following a set of steps in Reaper.
• Following a set of steps in Source-Connect 4.
• Recording on your DAW.

1. Create a folder for the Reaper session

On your computer, create a folder to save your session and the audio files in your session. Name it “Sample Reaper Session Files”.

2. Configure Reaper for recording

In Reaper, follow these steps:

a. Go to File > New project to add a new Reaper project.

b. Go to File > Save project as.

c. Save the project in the same folder you created in step 1 (in our case, in “Sample Reaper Session Files”). Name it “SampleSession”.

d. Go to File > Project settings. In the Media tab, make sure that Path to save media files (can be relative, leave blank for same path as project file) is left empty. That way, the audio files will be saved in the same folder as the .rpp project file.

e. Go to Track > Insert new track. This will add a new track to your project. Repeat this step twice to have two tracks. Name the tracks “TB Mic”and “Source-Nexus”

g. Click the FX button for the TB Mic track. Insert any volume plugin before the Source-Nexus I/O plugin. In the case below, we just inserted a “JS: Tone Generator” plugin (off).

h. Click the FX button for the Source-Nexus track. Insert any volume adjustment plugin after the Source-Nexus I/O plugin, but make sure it has +6dB in the adjustment area.

i. Make sure your tracks are record armed. You can verify or 

3. Configure Source-Connect for your session

In Source-Connect 4, follow these steps:

a. Go to the Restore/Replace tab.

b. In the RECORDED FILES widget, click the R/R settings button.

c. In the WATCH FOLDER PATH window, click “Set Watch Folder”.

d. Choose the folder you created in step 1 ("Sample Reaper Session Files").

e. Click the gears icon in the top right panel.

f. In the AUDIO I/O section, set CHANNELS to Mono.

g. In the AUDIO I/O section, select Source-Nexus B as your output.

h. In the Contacts panel, click your contact's icon and click the Connect button. Make sure both “Restore” and “Replace” are enabled.

4. Click “Record” in Reaper

In Reaper, click the red “Record” button in the Mixer. 

Then, go ahead and perform your session.

When you are ready to finish your session, click the “Record” button again to stop recording.

4. Wait for the recording to be displayed in Source-Connect 4

It might take some time for your recording to show up on Source-Connect 4 depending on the length of your session. For this sample session, we recommend a 1-minute recording.
