I’m not necessarily trying to record to any app aside from the Camera app on the iPhone (14 Pro Max). I want to take videos of my performances while getting the audio directly from the 16Rig mixer, via USB directly from the back of the interface. At one point, I got it to work with my iPad when plugging the USB-C cable directly from the interface to the iPad. When I tried it again, also with the 14 Pro Max, I got no audio. Is there something I need to set my Main L/R to on the matrix mixer? I figured you would just set the Main L/R to Monitor L/R, but that didn’t work.
