How do I use the "aggregate device" to monitor? What program should I be using to do the audio monitoring? I've got any audio going into Logic Pro (which is what I'm using for my audio) going into the Fireface, but outputting to Soundflower, so that it can be heard by OBS. I've created an aggregate device, and ticked both the Soundflower 2CH and RME Fireface UFX I've had a look at creating an aggregate device in Audio MIDI setup, but can't figure out how these works in terms of monitoring yet. I can get all of my audio into OBS, and am now able to see it all on the mixer meters (in OBS), but I'd like to be able to play along and the latency makes it impossible.

I am having a similar issue with OBS, an external USB audio interface (RME Fireface UFX) and Soundflower.
