Weird Overbridge routing bug

Hey, Guys. First time here. I’ve had my Rytm mk2 for about 3 weeks.

Is there a special way to record send effects on their own track via Overbridge? I tried turning off Route To Main for all voices. It seemed like this should work, but for some reason my MT/HT channel is still routing to main even with that track turned off. It kinds seems like a bug. Changing kits and restarting all the different system components doesn’t seem to make a difference.

Anyway, interested if this is a common issue or if I’m just unlucky. Using Overbridge on macOS with Big Sur. Latest Rytm firmware, too. Thanks for advice. Cheers!
