Thanks Bruce! Unfortunately, I can't find any way to set stereo/mono in my interface (Focusrite Control 2.3.4). The Hardware Input don't have any settings except for pan sliders (which would imply stereo!), mute, and solo. Only the outputs (headphones, etc.) have a button for stereo. In "Device Setting" I can set LINE or INST for Analogue 1 and I have it set to INST.

Hope that helps! Oh, and welcome to the forum!
