"This concert will not produce any audio output until you adjust the master volume"

Everytime I open MainStage 2.1.3 I get this message: "This concert will not produce any audio output until you adjust the master volume". I couldn't figure how to fix it so far. Please, someone help me. Thank you.

Look into the mixer on the right side: the master volume fader is set to -inf dB (all the way down), you have to move it up.


The reason why it is down, is probably to avoid feedback. If you have your mic and speaker both up and potentially close to each other, you would get immediate feedback which can kill your speaker (and your ears...). By making you move the volume fader up, you would notice it and be in the position to turn it down, before something bad happens.
