I use an Akai LPD8 Midi Controller to turn on and off 2 audio channels for my commentary announcers. I have the buttons setup to light up when the channel is on, and they can simply press the button to toggle the status of their audio.

This has worked great for more than a year, when suddenly a couple months ago, about 45 minutes into my production, the lights went dark and the buttons turned unresponsive. I still have control over the audio from my main vMix station, but nothing from the controller. This happened on vMix 20 as well as the new 21 install.

I have run a few tests and things seem to be working correctly, and I'm having trouble finding the cause. Any ideas? or suggestions on where to look? Thanks

EDIT: Just to clarify, it works again after a shutdown, but I can not reboot during my live streams to fix it, I just manually control the audio, which is not ideal most of the time.
