Measure in REW with output via RME

I have a 8 channel active setup. When I want to take a sweep in Rew I only have the option to playback one channel at a time. output is 1 to 8 but I want to measure the response on all of them.

I use Audiolense to create correction files. Playback in Roon.
 
It turns out that I still have a routing problem as REW can only send to one channel at a time.

Input is mic1. Soundcard is RME Fireface UCX

What is wrong here?

What other output options do you have? How is the Roon stream input to RME fireface, should be doing the same for REW.

I have an 8 channel DSP based setup with Linea Research ASC-48 and MiniDSP SHD Studio as the front end for volume control, and source selection. I use the USB input on the Studio for REW sweeps. The Studio is recognized as a 2 channel digital input.

I use Roon with an RPI4B/HifiBerry Digi-Pro 2 endpoint via spdif to the Studio. (It also is Roon ready but I prefer the external endpoint)

So I thought Roon was providing a stereo output to the RME and the RME took care of splitting into the 8 individual ways - I guess that is not the case. Do you have provisions for any stereo analog inputs? To do meaningful full range measurements you need to be able to drive all 4 ways for each speaker. (I can do that or just one at time if I want to look at a specific driver)

If I have understood correctly you are doing all of the DSP processing in Roon. (XO, EQ, level setting)

I don't think I have anything useful to add to this conversation unfortunately. I also have stereo RME hardware but it isn't structured like yours.
