What does mean on a soundboard?

"Mean" isn't a common term used on a soundboard. It's likely you're referring to a different word that sounds similar, or you're using a slang term that's not widely recognized.

To help me understand what you're asking, could you please provide more context? For example:

* What kind of soundboard are you talking about? Is it a physical mixing console, a software plugin, or a digital soundboard app?

* Where did you see this word? Was it on a button, a knob, a menu option, or somewhere else on the soundboard?

* What do you think it might mean? Any guesses or ideas you have might help us figure it out.

Once I have a better understanding of what you're looking for, I can provide a more accurate answer.
