Thank you for your answering my question. However, I know already that you have to raise the faders of the fx in the main bus and to send this FXs in the auxes. But with this, you will be needing another audio interface, am I correct?
I can route it to other auxes in the capture master however, you will not be able to select the what channel should be the input either in OBS or in MAC computer.
Can you guide me on this?
