metro stopping randomly
Video of the problem in action after applying Source Audio's fix. Notice the button coming out of metro, and how it just stops registering bangs and the midi output stops in the recorded loop.

Forgive me if I'm missing something obvious, I'm quite new and I've been trying to solve this for 2 days now.
I've included my Audio Status settings just in case.
Desired Behaviour: I want metro to only run while receiving Note-on, and I want to reset its count on Note-off, to drive a counter which in turn drives a grid.
Issue: metro will randomly stop sending bangs after stopping and then starting. It will always send at least one bang.
The issue is inconsistent, but seems to always start occurring some time after the patch has been opened in max device editor. Sometimes it will occur on a fresh load.
Steps Taken:
- I've confirmed the issue is with metro by verifying what is being sent to and from metro with messages and bangs
- restarting Max, restarting ableton, restarting PC
- configuring metro with as every combination of @active @quantize and @transport
- lots of experimentation with various on-load bangs like loadbang, live.thisdevice. Even when I can keep the metro running and just gate the makenote with velocity it behaves inconsistently (and I don't want metro to always scroll through the grid)
What's really making me tear my hair out though is that this was originally working at the beginning of the week. It's leaving a bad taste in my mouth with how inconsistent Max's behavior and I don't really know how to troubleshoot this further.
Any insight would be greatly appreciated, thank you.
