bens I was able to set the output port to my Quad Cortex, and I can scroll this settings ui, but I can't press done to dismiss it. Had to force quit. This was on macOS (10.15). I sent you the logs via email.
peter I can't reproduce this issue on macOS 15.7.4 which is the same that you use according to your logs.
bens my first thought was there was a midi loop happening, but after restarting it works fine. Would you be able to see that in the logs?
