My RME UFX II is working in multichannel mode with a Linux USB computer and Roon, which is excellent.

Last year I posted this:

Software fixes have been made in Roon such that this works now.

The Sonore microRendu is being used as a RoonReady device which talks back to a Windows 10 PC running Roon Server via ethernet.

I am sending 6 channels out for my digital crossovers into the UFX II.  Routing is needed in my application.

My workflow:

1) Measure my room with Microphone and Audiolense software using a Windows 10 PC connected directly to the UFX II via USB, using the Windows TotalMix app for routing.
2) Create digital crossovers using Audiolense on the Windows PC.
3) Import convolution filter crossovers into Roon.  Move PC out of living room.
4) Change UFX II to CC Mode.
5) Set up routing using the iPad TotalMix app (nice little app by the way!)
6) Unplug the iPad and plug in the microRendu, a tiny low noise computer running Linux.
7) Enjoy music with state of the art digital crossovers

This all works well, except the routing is not preserved over a power cycling of the UFX II.  Is there a way to preserve the routing?
