This section covers some common use cases for the 16i16 4th Gen. Often your use case is a variant of these and how you use your 16i16 4th Gen probably reuses some principles.
Using your Scarlett 16i16's line inputs, you can make it the central hub for recording in an electronic music setup. Most electronic music gear—synthesisers, drum machines, groove boxes, mixers, and effects—use line outputs, so with 6.35mm (1/4”) TRS jack cables, you can record and perform with your entire setup simultaneously.
The following diagram shows an electronic music set up with some mono and stereo synths, and a drum machine. Your setup might look a little different, but the principles are the same.
-
A stereo synth connected using two 6.35mm (1/4") TRS jack cables.
-
A stereo drum machine connected using two 6.35mm (1/4") TRS jack cables.
-
A mono synth connected using two 6.35mm (1/4") TRS jack cables.
-
A second mono synth, connected using two 6.35mm (1/4") TRS jack cables.
-
Headphones for you to monitor your performance.
-
A second set of headphones if you need them, or you could use this second headphone output for recording, see the Tip below.
Tip
Your Scarlett 16i16 can work in standalone. For a completely DAW-less setup you can disconnect your computer and use the line outputs, or spare headphones output, to send a stereo output to a portable recorder, or mixing console for live performance. See Standalone Mode.
The Scarlett has a standalone mode; this mode allows your interface to pass audio when it's not connected to a computer. This can be useful for:
-
Increasing the number of preamps on another interface or mixer that has run out of microphone preamps, for example:
-
Using any spare line inputs on the other interface.
For example, by routing the Scarlett's microphone inputs to its line outputs.
-
Using S/PDIF inputs/outputs
-
Using your ADAT inputs
-
-
To use your studio setup without having your computer turned on or plugged in, for example, to use your guitar through your speakers, or any electronic music equipment connected.
To setup Standalone mode:
-
Connect your Scarlett's power socket to mains power.
-
Connect your Scarlett to a computer running Focusrite Control 2. In Focusrite Control 2 's mixer page route the Scarlett's inputs to the outputs you'd like to use. See Using the Focusrite Control 2 Mixer tab.
For example, you could route your microphone inputs to your ADAT outputs to use your Scarlett as a standalone mic preamp to expand another interface with ADAT inputs. See Interface Mode to do this automatically.
-
Disconnect your Scarlett from your computer and it continues to pass audio in standalone mode.
-
Connect your inputs and outputs to your interface as usual (see Using your 16i16 4th Gen).
The loopback feature on your 16i16 4th Gen allows you to send the sound produced by your computer and route it back into your Scarlett for recording or streaming, without using physical cables. This can be particularly useful in various scenarios, such as sampling, podcasting, live-streaming, or recording screen tutorials:
-
Sampling: You can record sounds back into your software to use as samples in your music.
-
Podcasting: You can use loopback to record online interviews or discussions, where you want to capture both your voice and the voices of remote participants.
-
Live Streaming: It's useful for streaming content with accompanying audio from your computer, such as gameplay, presentations, or tutorials.
-
Screen Recording: When creating video tutorials or screencasts, loopback allows you to include the sound produced by your computer along with your narration.
To use Loopback, with your Scarlett:
-
Open your DAW or recording software.
-
Create a new recording channel in your DAW and either mute, or set the output to 'none' for this channel. It's important to do this so you don't cause a feedback loop.
-
Set your recording input of the muted channel to the Loopback channels of your 16i16 4th Gen, channels 9-10.
-
Start recording.
The channels in your recording software receive the output of your Scarlett. You can use other channels in your recording software to record anything connected to the inputs on your Scarlett alongside the Loopback feed.
You can also use Loopback to create a mix of any audio sources on your Scarlett, instruments connected to the preamps or audio from your computer. With Loopback, you can mix instruments and backing tracks for your online concerts or balance your microphone and game audio for your live stream. See Using the Focusrite Control 2 Mixer tab.
Important
When you're using Loopback, mute the channels in your recording software so you don't cause a feedback loop.
