Thats great about being able to create multiple output destinations for each signal, actually thats really freakin' cool lol. However what about the monitor signal coming in from the mixing board, can I bring that in and only assign its output to the headphones? From your answer it seems that the usable signals (guitar, vocal) can be routed wherever, but since the signal from the mixing board would not be a path being used such as vocals and guitar, will I be able to put that signal only into the headphones?
As far as my second question, in similar way, is it possible to route multiple paths to come out the same output for instance, just have vocals and guitar come out one mono output?
