Description of Issue

Hi, I am using Roon as a source and active crossover.
My Roon Rock NUC provides all procedural PEQ for the 3 way crossovers.
This feeds a RPI4 running Ubuntu/Roon bridge, which connects via USB to a Motu MK5 lite.
Everything works perfectly, including sample rate changes.

I am tring to understand how I could use REW to provide measurements/sweeps, without resorting to local playback of stored sweep files to mimic the frequency sweep playback of REW.
This method limits REW capability, to only RTA.

Is there any way Roon can provide an auxiliary input (I.e. using virtual cable, etc), to allow REW to output back in to Roon for playback through the procedural crossover?


You can record all possible REW test signals through it’s generator tab and even include a timing pulse to use all measurement features… check out the documentation…


Thanks for the heads up.
I had never used REW that way, so your suggestion is very helpful.
I can see the generator, and I understand how to export the file… I will play with the function, and the timing reference. Thanks
