Hi, I’m just getting acquainted with the UCX II and I foresee myself using it as a standalone playback device often. However I’m puzzled at the way the Mic/Gain button only allows access to inputs 1/2 and 3/4…why not the rest of the inputs? Especially since in the manual RME suggests this is a useful device for live performance. Do I have to adjust levels on instruments plugged into line inputs 5/6 and 7/8 on the computer and then load those stored settings into the interface?
