⚙️ What To Do If You're Seeing "License Not Found"

If you see a message like "License Virtual Microphone System Not Found", it likely means you're trying to use the wrong plugin for your license or microphone model.

Here's what you should do:

• If you have an ML-1 and no subscription, uninstall the Virtual Microphone System plugin. You should be using Virtual Mix Rack instead.
• You can uninstall the incorrect plugin using the Slate Digital Connect app. Click the three vertical dots next to the plugin and choose Uninstall.

✅ What Should ML-1 Users Install Instead?

You’ll want to install Virtual Mix Rack (VMR), which includes the following licensed content for ML-1 owners:

• 🎙️ Classic Tubes – 8 microphone models
• 🔊 Virtual Preamp Collection – FG-76 & FG-73
• 🆓 Free Rack Modules – Monster, Revival, Trimmer

👉 Download Virtual Mix Rack

Note: Your DAW (e.g., Logic Pro) must be closed during installation.
