Hi, Really hope you can help but i'm having issues with the mixtone. Presumably a dumb question since I'm a newbie but.... I've tried on two different soundcards. Using the XLR from soundcard in stereo I seem to get a side mix. If I force the soundcard to mono I get an extremely quiet mono single. Even with the volume on the back of the mixcube turned up it's still no good for mixing and if i accidently switch out of mono the volume is deafening. Using an audiojack the audio seems to just be the left channel. Is this how it's supposed to be?
