How I Route Reaper to the X32 using VB Matrix (Complete Setup)

Welcome to Reaper to X32 masterclass. If you've ever tried mixing live broadcasts on Windows, you already know the ultimate frustration: Windows limits your DAW to a single ASIO device, making complex master and monitor routing an absolute headache. In this tutorial, we break through that ecosystem limitation. By pairing the power of VB-Audio Matrix with REAPER’s long-awaited "Dedicated Solo Bus" feature (introduced in version 7.46), we unlock true, hardware-console style routing right on your PC. I’ll show you step-by-step how to aggregate multiple audio sources, isolate your headphone monitoring via the new REAPER solo bus, and keep your master stream mix completely uninterrupted for your audience—all running flawlessly without crashing your ASIO drivers. What you'll master in this video: 🔗 Breaking the ASIO Limit: How to use VB-Audio Matrix to bridge multiple audio devices seamlessly. 🔗 REAPER Solo Bus Setup: Enabling the native dedicated solo bus preference. 🔗 Advanced Hardware Routing: Assigning separate "Always Master" paths to OBS and "Solo Active" paths to your physical monitors.
