I know many of you are on the new logic, I hope to get a mac in the near future. I would think the busing works the same still. My friend helped me set this up a few years ago so I just saved a template. I'm trying to understand the signal flow. I had a few questions, but it's kind of difficult to ask. -------- So right now I'm bringing in a M1 LX multi effects unit via an Auxiliary in logic. Inputs 5-6 in the aux channel are where it comes in from the outputs 5-6 of my audio interface. NOTE: I don't know why I have to specify an output (example 1-2) in the auxiliary if the bus is bring the wet signal into the channel I'm applying it to? Channels have their own outputs, so why do you need to specify an output for the aux? I have to or it won't work. That's my first question. Regarding the bus: Logic's bus channels in v5.5 only have one place to select an input. In this case it's displayed as outputs. So this output section must be the audio interface's outputs that the bus grabs it's signal from (the wet signal). So when I increase the bus level on the audio channel, is it safe to say that logic is sending the dry channel signal to the auxiliary (which is where the effects unit is connected) then that wet signal comes back into logic and is mixed into the audio track? I understand the concept of routing, but I don't understand where and to what the signals are being routed to without some kind of visual diagram.
