Hello,
I just purchased my first RME device and installed it in kernel driver mode on my Intel Mac.
(My previous antelope audio Original Zentour model died.)
The new RME sounds excellent and latency is reduced.

I have watched a few videos and picked up how to create and save a basic Mix and host to add or remove routings via the Mixer and Matrix View, also experimenting with the the RME Loopback function.

One of the things I had configured on my old interface was to be able to play online with other musicians in FarPlay, Jamulus, and Sonobus. (but mostly FarPlay due to the audio quality and multitrack recording)
It admittedly took some amount of tweaking getting my old interface to work in these apps but once I did it worked for all three apps.
Initially I tried joining a session with the RME but my audio was not playing in the session.

The old interface did work for all 3 apps and I was also able to run Gig Performer 5 on a second audio interface built in to my Roland RD-88 and make that part of the mix.
Since this is my first experience working with Total Mix and have only an early understanding of it's routing system I am appealing to the forum community members who have used their RME interface in this context with this apps for assistance creating a basic mix that will work.

Thank you.
