This started out as a bug report as I couldn’t hear the audio from my Zoom H5 (4 channel recorder) when using Audio Analysis with Pass-Thru enabled, but I think VDMX is respecting the channels as it turns out 1 and 2 work but not 3 and 4. My destination is HDMI and my monitor only supports stereo audio, apparently.
I appreciate this may not be a high priority or frequent request, but it would be useful to me. :-)
