Hi there,
Goal: Streaming a DJ set (using Djay Pro software) via OBS, while using a Duet 2 USB as my audio interface— sending my main mix out 1/2 speakers, and headphone mix out 3/4. I've installed Soundflower as my internal audio router, which should allow me to send to both OBS and my interface, by creating a multi-output device.
Problem: When I set everything up as instructed— routing Djay Pro Main out to Multi-Output Device, and pre-cue out Duet 3/4—I run into two issues. 1) I don't hear any audio coming from 3/4 headphone mix, and 2) my OBS does not register any audio from my Soundflower 1/2 output device. I've done a ton of troubleshooting with various combinations of applications + I/O etc, and deduced that the problem must be between the multi-output device and the Duet, or possibly with Djay Pro's ability to work with multi output devices. Otherwise Soundflower is routing to OBS just fine without the multi-output device, and all 4 outputs on my Duet are working fine without it as well. So in the end, I can EITHER send audio to OBS via Soundflower and lose my main outputs, OR send audio to my main outputs and lose my Soundflower>OBS connection.
Please advise! Thank you.
My system:
MacBook Pro (15-inch, Mid 2010) running OS X 10.13.6 High Sierra.
I have the latest OBS release (25.0.8) and Duet 2 USB firmware.
Djay Pro v1.4.5
Soundflower v2.0b2
