Setting up your Audio Interface - Part 2

by Marcus Dellicompagni on June 26, 2019

Welcome to part two of How to Setup an Audio Interface (with Windows 10). Please ensure you have read the previous tutorial on how to set up an Audio Interface, before continuing with this. In this tutorial, we'll be looking at how to set up your Interface with Cubase 10, covering the basics to get you ready for recording.



Before recording audio, Cubase needs to know which audio driver to use for recording and playback. Once Cubase knows which device and driver to use, we can start configuring the inputs and outputs.

Let's start by opening the audio settings in Cubase 10. From the top menu select Studio > Studio Setup. This will bring up the Device Menu. Located to the left of the Device Menu you'll notice a list of menus for setting up various things. Obviously, we need to set-up the audio driver.

From the list select "VST Audio System". On the right of the Device Menu, there'll now be a drop-down menu for selecting the Audio Driver called "ASIO Driver". Click the down arrow and select your interface from the drop-down list. Finally, click on "Apply" at the bottom. If your interface is not showing in the list, please go revert to the previous tutorial.



An Input is used to send a signal is sent directly into the interface, for example, a microphone or instrument. An Output is used for sending a signal from the interface to another device, for example, to your monitor speakers, headphones or outboard gear.

Setting the inputs and outputs for the interface in Cubase relatively straight forward. All we need to do is tell Cubase how many inputs and outputs the interface we wish to utilise.

To open the Audio Connections menu press F4 on your Keyboard or from the top menu select Studio > Audio Connections. The Audio Connections box will now appear with 6 different tabs to choose from. For this tutorial, we'll be focusing on using the "Inputs" and "Outputs" tabs.

First Open the 'Input' tab. We need to tell Cubase how many Inputs of the Interface we wish to use for recording. First, remove any existing inputs by right click any input bus then selecting 'Remove Bus'. Once we have removed any Bus(s) we can create our own. To create a new bus click the "Add Bus" button. This will open a pop-up menu with a couple of options.


  • Count - determines how many bus's you would like to create.
  • Configuration - determines if you are using a Mono or Stereo input.
  • Speakers - Allows you to assign the output to different speakers (if available)
  • Bus Name - Allows you to name the input(s)

When creating a new bus, it's important to create them in Mono unless you plan on summing two Mono sources to a Stereo channel. For example, If two microphones are used to record in Stereo, such as Drum Overheads or Acoustic Guitars, and we would like both microphones to be summed to 1 Stereo fader.

If a "stereo" bus is used for recording a mono input, you may find the recording only appears in the left or right speaker. This is because the Left & Right speakers will be assigned individual inputs from your interface.

For example, Left = Input 1 and Right = Input 2. If you record a Vocal on a Stereo track via input 1 of the interface, Cubase will play the vocal back only in the left speaker. This is why it's important to create & use Mono Bus(s) instead of Stereo as 1 Microphone or D.I = 1 Mono Input.

Depending on the interface, the number of inputs you need to create will vary. For example, an interface with 2 input channels will require 2 Mono inputs. An interface 4 input channel will require 4 mono inputs etc...

Next, we need to ensure the outputs are set so we get playback through speakers & headphones. In the Output tab, Cubase should have automatically created a Stereo Output with the Left and Right channel assigned to the Output(s) for the interface. To check, simply look to see a Stereo Bus has been created with the Audio Device column listing your interface and that the outputs as 1 & 2 for the interface.

If a Stereo Bus has not been created, or the Audio Device column is not listing the interface, simply Add a new Stereo Bus then in the Device column select your interface and make sure the Left and Right speakers are assigned Output 1 & 2 of your Interface.

If you plan on using the MediaBay, consider using the "Control Room" tab to handle all Outputs otherwise any content being previewed through the MediaBay will not be heard. The Control Room offers advance output functions such as routing to multiple speakers, creating headphone mixes, assigning talk-back and more - while also providing additional monitoring control & functions in the mixer such as Stereo > Mono, Dim, Metering Options etc... I highly recommend using the Control Room by default for setting up your Outputs.

You can also use the save & load presets feature to store or recal configurations.


Now that the Input(s) and Output(s) have been set you we can now create Audio Tracks for recording. To create an Audio Track simply click the + symbol then select "Add Audio Track". From the pop-up menu select the Input you wish to use for recording, ensure the "configuration" is set to Mono and select the Output you wish to use.

Once the track has been created, click the Arm button to prime the track for recording and if you need to hear the signal, click Monitor button. That's all there is to it, you're now ready to record. Simply press the record button in the play-bar and get rocking!

In some cases, you may need to use Stereo audio track while selecting a Mono Input. Most notably for Amp modelling software as they usually take the Mono Input signal and split it to Stereo for things like dual Head & Cab emulations, where both Amps are panned L & R (in the software) and the effects work in Stereo.
