How to configure Cubase/Nuendo and Source-Connect 4 Studio/Facility to record incoming audio signal
The following is a sample, step-by-step template that will ensure you can record incoming audio signal in Cubase/Nuendo and Restore/Replace in Source-Connect 4 Studio/Facility using the Source-Connect I/O plugin.
Your project, audio tracks, and configuration in general, might not be similar - keep in mind this is just a simple R/R template (100% tested though!).
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 Cubase/Nuendo.
- Following a set of steps in Source-Connect 4.
- Recording on your DAW.
1. Create a folder for the Cubase/Nuendo session
On your computer, create a folder to save your session and the audio files in your session. Name it “Sample Cubase/Nuendo Session Files”.

2. Configure Cubase/Nuendo for recording
In Cubase/Nuendo, follow these steps:

3. Configure Source-Connect for your session

4. Click “Record” in Cubase
In Cubase, click the “Transport Record” button at the bottom of the screen and start recording:

Then, go ahead and perform your session.
When you are ready to finish your session, click the “Stop” button 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.

And you are done! There will be a new recording in the “CONNECTIONS” panel with the name of your connection partner.
