macOS multi-channel audio routing in Isadora

I have just completed the task of routing multi-channel audio through Isadora from DAW software (Logic Pro). I compiled the steps into a short PDF document. But I am wondering if there is any other way to do this? 

I was unable to capture, through Live Capture Settings,  the multi-channel audio through my audio interface - not sure why Isadora refused to see any more than one stereo track when capturing directly from my Focusrite audio device. After routing through a multi-channel virtual audio interface (Loopback Audio) I did manage to get independent control and SoundLevelWatcher++ data for each channel. Then mix out of Isadora using AU plugins to my audio hardware.

Any best practice tips for this exercise?
