Virtual Devices
RØDECaster Beta Program
Please note that the virtual devices feature is currently exclusively available through the RØDECaster Beta Program. If you would like early access to the virtual devices feature, and to be the first to hear about new features and updates, please sign up below.
Note: While in beta, the virtual devices feature is only compatible with Windows computers. Mac compatibility will arrive with the full public release of the update.
What Are Virtual Devices?
The audio that your computer outputs is a stereo mix containing sound from all of your software at once. As an example, this mix might include a music streaming app, a web browser, a game and a chat application. This software will either have its own volume control or, in the case of web browsers, rely on volume controls on the pages you have open, such as YouTube.
Virtual devices allow you to treat your software as if it were a microphone or instrument connected to your RØDECaster. This means you can assign software to a fader, giving you hands-on volume control over all your software’s audio in a single location. It also gives you the ability to apply effects and processing, create custom routing, and record each software’s audio separately.
Enabling Virtual Devices
First, install the Virtual Device Driver and then restart your computer. This is required for your computer to separate the audio from multiple pieces of software and communicate them to your RØDECaster.
Ensure your RØDECaster is running the latest firmware by navigating to Settings > System > Info > Check for Update while connected to a network via Wi-Fi or Ethernet.
Next, on your RØDECaster, navigate to Settings > Outputs > Multitrack > USB 1 Input and tap “Expanded”.
Note: When using virtual devices, your computer will be handling some of the audio routing and mixing that was previously done by your RØDECaster. This extra processing can rarely result in some audio artefacts, depending on your computer’s processing power. To help mitigate this issue, you can click on the Virtual Device Driver tray icon and under ‘Latency’, toggle the setting from ‘Ultra-low' (default) to 'Low'.
Assigning a Virtual Device to a Fader
Press the button above a fader, or tap the on-screen icon below a channel’s level meter, then tap the settings cog to access the channel assignment screen.
Here you can select which input is assigned to that channel, including any of the four new virtual devices – Game, Music, A and B. Once you have chosen, tap the green tick icon to save the settings.
Note: All four virtual devices are functionally identical – you can assign any software to any channel – the naming convention is simply an organisational aid.
Assigning Software to a Virtual Device (Windows)
With virtual devices enabled, and your RØDECaster connected to your computer via USB 1, the virtual devices will appear as outputs to your computer.
Ensure that all of the software you wish to assign to a channel is open and running, then navigate to Settings > System > Sound > App Volume Device Preferences.
This screen will display all of your active software, each with its own volume fader, input and output. Here, you can select one of the virtual devices as the output for the software you wish to assign it – either Game, Music, A or B.
Note: There’s no need to adjust the volume faders here as they will be overridden when assigned to one of your RØDECaster’s faders.
Multitrack USB Output
Multitrack USB audio allows you to record or stream each of the RØDECaster’s channels separately. When you have enabled virtual devices on your RØDECaster and installed the Virtual Device Driver, it allows access to a new multitrack USB output mode.
This mode outputs each of the RØDECaster’s channels to your computer as its own USB audio device, which is ideal if you’d like to route them within streaming software such as OBS. This differs to the typical multitrack output, which is a single audio output device with up to 16 channels, which is more optimised for use with DAWs and similar software.
If you predominantly use the RØDECaster with the Virtual Device mode enabled, but would like to temporarily access the typical multitrack output for use with a DAW, you can right-click the Virtual Device Driver icon in your system tray and click “Bypass”. When bypassed, you won’t have access to the virtual devices (Game, Music, A and B), but all your fader assignments and other settings will remain in place for when you un-tick "Bypass”.
