Just wondering what the advantage is of having presonus etc if it seems I can set everything up on my fireface mixer I have 1/2, 3/4, 5/6 open for just speakers outputs. Should I go that route right now and set up 1/2 and 3/4 for two different sets of speakers and 5/6 with the mono setting in fireface mixer for just one speaker (behritone c50a) (plugged into output 5)
