I have two vMix Pro systems running on rack mounted machines. Each has a Skaarhoj Air-Fly panel connected to it, and they work properly. I've noticed however that if my vmix project contains an extra Mix input, the Green/Red button colors for preview and program buttons will follow the mix input's pvw/pgm, and not the main mix. I emailed Skaarhoj and they said they were working on it, but that it was likely a limitation with vMix's web API. Has anyone encountered this issue before, and does anyone know of a possible workaround?
