The Client’s Challenge
A client reached out with a challenge that every home recording artist knows well. While recording vocals in Cubase with their Focusrite Scarlett 6i6, they found themselves in a constant battle with headphone levels. If the backing track was at a good volume, their own voice felt lost. If they turned their vocal track up in Cubase to hear themselves better, it would record too hot and risk clipping.
It’s a frustrating cycle: you can’t perform at your best if you can’t hear yourself properly, but the very act of adjusting your monitor level seems to compromise the recording itself. The client felt they were missing a simple trick, and they were right—the solution wasn’t in Cubase at all, but hidden in plain sight within the interface’s own software.
Diagnosis: Separating What You Hear from What You Record
The core of the issue lies in a common misunderstanding of signal flow. When you adjust a fader in your DAW, you are changing the level of the signal *within the software*. This affects both what you hear on playback and what gets recorded or mixed. The client needed a way to create a separate, personal headphone mix that wouldn’t interfere with the levels being sent to Cubase. This is often called ‘zero-latency monitoring’.
The Key Concept: The Onboard Mixer
Modern audio interfaces like the Focusrite Scarlett series are not just simple inputs and outputs. They contain a powerful internal digital mixer. This mixer can take audio directly from the microphone input and blend it with the playback audio from your computer (Cubase) *before* sending the combined result to your headphones. The tool to control this mixer is the Focusrite Control software.
My suspicion was that the client was monitoring their vocals *after* they had made a round trip through Cubase, a process that introduces latency and ties the monitor volume to the DAW fader. By leveraging the interface’s direct monitoring capabilities via Focusrite Control, we could create a custom, latency-free headphone mix with the perfect balance.
The Fix: Crafting a Custom Mix
The solution was to guide the client through the process of creating this custom headphone mix. It’s a few simple clicks, but it unlocks a professional workflow that makes recording a far more comfortable experience.
Open the Focusrite Control application. This is the control panel for your Scarlett 6i6 interface.
In the ‘Output Routing’ section, find the output that feeds your headphones. For the 6i6, this is often Line Output 3-4.
Click the dropdown menu currently assigned to that output. By default, it might say ‘Playback (DAW) 1-2’. Change this to ‘Custom Mix’.
A new mixing panel will appear. You will see faders for your inputs (e.g., ‘Analogue 1’ for your mic) and your DAW playback (‘Playback 1-2’ for Cubase). Now, simply adjust these two faders to create the perfect blend of your live voice and the backing track in your headphones.
Visualizing the Custom Mix configuration in Focusrite Control.
The client was delighted. They now had an intuitive, tactile way to control their monitor mix on the fly, completely independent of their recording levels in Cubase. The problem wasn’t a fault, but simply an undiscovered feature.
Additional Reflections: The ‘Stage Mix’ vs. The ‘Front of House’ Mix
A helpful way to think about this is to imagine a live concert. The sound engineer at the main mixing desk is creating the ‘Front of House’ mix—the balanced sound that the audience hears. This is your Cubase project.
However, the singer on stage has a small speaker at their feet, called a monitor wedge. The mix in that wedge is completely different; it’s their personal ‘Stage Mix’, likely with their own voice much louder so they can stay in key. They need to hear something different from the audience to give their best performance.
Using the Custom Mix feature in Focusrite Control is exactly like giving yourself a dedicated monitor wedge. It empowers you to create the perfect monitoring environment to capture your best take, without ever touching the ‘Front of House’ mix being recorded in your DAW.
