This is partially from a response to a 7.1.4 workflow example that I posted elsewhere. The difference here will allow you to monitor in binaural.
1: Go to Preferences>VST>VST Control Room) Then enable “use phones channel as preview channel
2: Create a headphone monitor group under the control room tab and assign your L & R headphone outputs to it
3: Create a 3rd order ambisonic bus under the outputs tab and assign it as the main mix
4: Create a group with 7.1.4 in & route that to the 3rd order output bus.
5: Place the Atmos Renderer plugin on an insert for the 7.1.4 group you just created.
6: Create a group with a 7.1.2 input and route it to the 7.1.4 group. This group will now be available as your “bed track” source under the “adm renderer settings” in the project menu.
7: Create a group with a mono input and route it to the 7.1.2 to 7.1.4 bus last created. This can be now panned as desired and sent to LFE from the multi-panned.
8: Route the output of your source audio track or VSTi to the mono to 7.1.2 group. This will fold a stereo source now to mono for more localized panning.
Hope this helps you along the way and have a great New Year!
