I have my Kemper main outs (L & R) going into my Motu M4 interface ins (1 & 2). When I use stereo effects from Kemper, I can hear the stereo field just fine from the Kemper headphone jack and from the Motu headphone jack when interface is in playback mode. However, if I turn the Input Monitor Mix knob down to 'Input" then I loose the stereo field and the sound is quite a few db's lower in volume. I suspect this has more to do with the interface itself than the profiler. But what would cause this to happen? Is there some setting in DAW, Motu, or the Profiler I need to set?
