Is there a quick way to set the output of NS to mono? I'm playing a pub gig tonight and the speaker placement is such that stereo will not work well (the layout and acoustics of the environment and speaker placement mean that the crowd will be near to one speaker or the other). Is there a quick way to set NS2 to output in mono? I know I can change the iPad to output in mono in the system settings, but if I can quickly switch NS to mono that would be a lot easier. Thanks in advance!
