Ok, here is the situation.
A: I play in a band with IEM-solution on stage. I send my signal to the rack, band signal goes to my wireless iem. this gives me live no option for a change in the mix
B: On the other hand i also play alot along with music from my mp3 player. I use the alternative input and return input to input the mp3 player.
In Theory, i could keep the same setup without changing much buttons. i could use the main outs to pa (i need the xlr's) and monitor out-direct out to my in ear. Band-mix comes in with the alternative input and return input.
Problem with this is that i can't mix the Aux-in stereo to my iem mix.
This is easily solved by mixing aux in>direct out in the kemper. (And there happens to be a knob left )
What do you say?
