Hey so like the description said my headphone outputs are all mono for some reason, yet my main mix (to my monitors) are stereo. I'm assuming this is an issue with my understanding of the Universal Control software because as i was playing around with it trying to figure out what is going on i at one point or another got my headphones to output stereo and got the second headphone out to work, but honestly i have no idea what i did and now its not working again... Does anyone know how i can get both of my headphone outs to be working simultaneously and to be stereo? I also have no idea what the A/B button is supposed to do and the user manual isnt very helpful on the matter.
