Setting up the RØDECaster Pro Multitrack with Pro Tools on a Mac can seem complex due to how the device manages inputs and outputs. However, with a clear step-by-step guide, you can easily use its multichannel features alongside Pro Tools.
The RØDECaster Pro appears as two audio interfaces: RØDECaster Pro Multichannel (14 input channels, no outputs) and RØDECaster Pro Stereo (2 output channels for monitoring). Since Pro Tools only allows one audio device as the Playback Engine, you need to combine these into one device.
The solution is to create an Aggregate Device on your Mac, merging the Multichannel inputs and Stereo outputs for use in Pro Tools.
Follow these steps:
-
Open Audio MIDI Setup: Find it in Applications → Utilities. It shows all audio devices including the two RØDECaster Pro interfaces.

- Create Aggregate Device: Click the plus (+) button, select “Create Aggregate Device,” then check both RØDECaster Pro Multichannel and Stereo devices. Rename it (e.g., “RØDECaster Pro Aggregate”).

- Open Pro Tools: Create a new session and select the Aggregate Device as the Playback Engine. Pro Tools will set the sample rate to 48 kHz automatically.

- Set Up Tracks: Create audio tracks matching your inputs—e.g., stereo tracks for stereo sources and mono tracks for microphones.

- Configure Input Routing: In Pro Tools’ I/O Setup, rename input channels to match your RØDECaster Pro’s physical inputs for clarity.

Following these steps lets you record multiple microphones and stereo sources simultaneously with high-quality playback. If you need further help, feel free to reach out.
