Quick question - can I send audio to the individual outs on Rytm?

I know that I can:

-use the Rytm as a stereo out from my DAW (to gel audio with the compressor)
-send audio to individual tracks to process with the filter and overdrive, then send back into the DAW

If I were to hook up 1/4" cables to the Rytm’s individual outputs, could I use it as just an eight channel audio interface? I am scheduled to do an eight channel performance later this year, and my current interface only has 6 outs. Using the Rytm just as an interface (and maybe some gentle filtering) would save on buying or renting more gear:)
