Duplicate stereo outputs in output routing list

Software / Hardware

  • macOS 26.6 (MBP 16 M5)
  • Cubase 15.03 Pro
  • Antelope Audio Orion Studio Synergy Core (32-in / 32-out)

Issue

  • Map your interface inputs / outputs.
  • Save the mappings as a template in the Audio Connections for both inputs / outputs.
    • In my case, for Inputs I have 32-mono first and 16-stereo second. I have Mono 1 set as the default input.
    • For outputs, I also have 32-mono first and 16-stereo second. I have Stereo 1 set as the default output.
  • Close Cubase.
  • Reopen Cubase.
  • Create an audio track.
  • Select output routing and see there are a number of duplicate stereo outputs: some have drop downs for L/R others don’t. See below.

On this step are you creating a new Project from the Template where you saved your configuration, which should retain your Inputs & Outputs; or are you just starting from scratch in which case you’ll get a generic set of Ins & Outs?

If I’m not mistaken (?) only the stereo ones have two entries and the point is giving you access to child-buses when expanding the ones with the triangle next to them. In other words click on the one without a triangle if you just want to route into the stereo path “as stereo”, and select one of the child-buses (“Left” or “Right”) if you want to route your signal to only one of them instead.

So it’s not a mistake as far as I can see.

For each stereo out bus there should be two entries: One is for the bus as a stereo bus, the other one lets you select individual outs of that bus.
I’d say this is like it is for everybody and by design.

:thinking: :roll_eyes: :face_with_bags_under_eyes:

Could you post an additional screenshot, showing the Studio > Audio Connections > Outputs panel, with all the items fully expanded (using the + button on the top right of the window) ?

Is my first reply invisible or something?

Since it has been explained and I understand its purpose now. Maybe a better way of displaying it that is less messy could be implemented. Like selecting the the one with the arrow (parent) selects L/R, then you can expand to select either L or R. Or a toggle to turn it off.

I think that the culprit is rather to be found in the driver direction, or is it a MacOS thing ? On my end, I can’t get any duplicate in the audio outputs routing list, no matter how I set output busses from the available hardware ones. :thinking:
