Yesterday, when recording with the Cubase Pro, 10.5.12, I encountered an issue I don’t recall previously. I wanted to simultaneously record two mono tracks (vocals and guitar). I used the Cubase “audio connections” panel to create 6 mono inputs and then connected microphones to inputs 1 and 2 of my interface, the UR44. While checking input levels on the mixer panel, I noticed that the signal from input 1 was showing up as signal on both “mono 1” and “mono 2.” For example, if I tapped on the microphone going into “mono 1,” I’d see equal signal levels on both “mono 1” and “mono 2.” To avoid this problem, I eventually found that needed to pan “mono 1” fully left and “mono 2” fully right. However, this workaround was not the best for monitoring while recording, since I was hearing each of the two tracks panned hard left and right. I would have preferred to have both panned center while recording. (I’ve realized since then that I could perhaps temporarily adjust the panning of the “stereo out” bus to allow me to monitor in mono or close to mono.) I tried disabling the “mono 2” input and using “mono 3” or “mono 4” and the second input, but the “mono 1” signal always showed up in the second track unless it was panned hard left.
Anyway, I’m hoping someone can explain why my input routing behaves this way. Given the routing I had set up, I can’t understand why the signal from “mono 1” would show up in “mono 2” and why panning “mono 1” hard left would remove the “mono 1” signal from the “mono 2” input. I’ll appreciate any explanations or advice for a better way of setting up the recording interface when I want to record two microphones on two separate mono tracks. Thanks.
