Hey Roelj, I’m trying to figure out a way to play audio through my QC (so I can play a sample for my band’s live intro) and stumbled upon this post. I have an android phone + a USB-C to 3.5mm adapter already. How would I set/connect everything up so I can play some audio that would go to the XLR out (and FOH)?
Hey @ChrisBlock . Sorry for the late reply, I don’t visit the forums often anymore. If you are still looking for a solution then we can try and get the android app working for you.
You can find my contact details on Github (GitHub - roelj/QCCompanion: Android App to use with a NeuralDSP Quad Cortex.), or private message me. 
that is a wonderful idea… I have been using Headrush products before I got my QC but all headrush products had the feature that you can play mp3 files with the looper. you can actually play and stop with the foot switches as well… I am really surprised how QC doesn’t have this feature…
