Ok. I have stumped myself and I can usually figure these things out given enough time.
Was building a show on GLD editor. First in long time. First in 1.51. First in Win 10. Got it built. Loaded it into console. Everything seemed fine except no Main output. PAFL on Main worked but no output. Not with input or tone. Oddly with this config from the editor. Mix is labeled MAIN but says 1. Not LR. Meter shows signal present but nothing on meters or phones. I load an old show back in and it works fine. Load new show and nothing. No DCAs are turned on. No reason for this not to work.
Any ideas?
