Question / Help is it possible to use multiple outputs on my audio interface and route audio to each one independently

[lewis0302]

I’m streaming a live music show and the microphones and instruments are going into a UAD Apollo interface for mixing. The audio is then sent out into a second computer with a Motu Ultralite AVB along with the camera through a capture card.
This is all working great and the stream looks and sounds really good.
However, we are doing a video Q&A and I want to be able to send the audio out from a media source on a separate channel to the main output, while simultaneously sending it to the main output. I want to be able to use the multiple outputs on my Motu audio interface and be able to route audio to each independently. Is this possible?

I want to be able to send the audio out from a media source on a separate channel to the main output, while simultaneously sending it to the main output.

Can you rephrase this? Are you trying to setup a mix minus or do you just want a duplicate main output with 2 separate versions, 1 with the extra media source and one without the added feed. ?

Hi Vapeahoy, I want to have my full mix out and then an additional out with only the audio from the media source going to a separate output on my motu.

OBS can't do this itself, you'll want to look into third-party software like VBAudio VAC, or Voicemeeter.

Hi Vapeahoy, I want to have my full mix out and then an additional out with only the audio from the media source going to a separate output on my motu.

If you want to do this in hardware you would need to split the signal and add an effect stop, a pitchstop if u will, where you can combine the additional media source with the full mix. If you have enough I/O left in the motu that should be the way to go.
If you want to avoid splitting signal, you'll need to duplicate it from main mix out, using a combination of stereo and main outs, on my mixer i'd use group 3-4 and aux 1/2 or stereo 1/2. Or since i have 4 outs from main on mixer just group 1,2-3,4. Then in the mixer i could use FX send it into the group 3-4 use separate the out from that using FX send or such.

So yeah, this can be done, but you might need some new hardware.
