Hey, if you plan to update to 1.4 please, save scene/show, after update, if your master fader is not working, well, it shows changes everywhere (in app, on screen etc), but doesn’t actually output any sound anymore, then do this:
1) in Setup -> mixer config Reset Mix to Standard
2) Scenes -> Scene Manager -> Recall Filter -> Mix TAB and under the Main section BLOCK processing, then recall your mix as usually.
This should save you some minutes. Huh, for me it almost ruined the event!!! ;p
