In the ad External instrument dialogue, We are prompted for mono and stereo " returns." I don’t understand the terminology here. Why is it called a " return?" For something to be returned doesn’t it have to first be sent? Audio goes from my synth through my interface to cubase. One Direction. What am I missing?
FWIW, I have the same problem, and recently found out the etymology of many of the terms inherited by DAWs and general in-the-box audio technologies come from large format mixing boards. I had to do a project at Berklee where I was creating signal flow diagrams for a Neve console and it was making me crazy. When we got to creating cues and aux tracks in the DAW, the instruction was some crazy, complicated combination of sends and returns and remapping faders and such and I just included a screen shot of my mixer in Cubase with an arrow pointing the the Cue Sends and CR set up.
I think ProTools even has separate “aux” tracks specifically for that reason, even though I would just create a track and send it wherever I wanted.
