Hi @SteffenR!
We use speakers for monitoring (not headphones). In this case, I don’t want to give monitor mixing to musicians (it can cause serious feedback problems).
Instead, I give monitor mixing to my colleague, who helps musicians on the stage.
MixPad seems to be better solution for this than SQ4You.
On the other hand, I don’t want to give a chance to others to change FOH mix.
I think, this is a good way to separate responsibilities.
BR, Gábor
