What is the correct path to configure a 2-in, 2-out USB interface as the default I/O for new sessions?

• A. The I/O setup is automatic; no action needed.
• B. Preferences > Audio I/O > Default.
• C. Use a template project only.
• D. Setup > I/O > Input and Output tabs: map 1-2 to your interface inputs/outputs, and click Default to apply for new sessions (or save as template).

Answer: (D)

Setting the default I/O for new sessions means configuring Pro Tools to use your USB interface’s channels as the standard input and output for every fresh project. You do this inside Setup > I/O. On the Input and Output tabs, map the first two hardware channels (1–2) to your interface’s inputs and outputs, respectively. Then click Default to apply this routing for new sessions (or save the setup as a template). This ensures every new session starts with the same hardware routing. The other options don’t establish a persistent default: it isn’t automatic, Preferences doesn’t set the default I/O, and templates are a workaround but require saving the correct routing as a template or default.
