I only started noticing this delay a couple times. I noticed it happening a once or twice a couple weeks ago. And if I recall it didn’t happen on the same scene. And it has not happened ever single time when switching to the scenes. I know that we updated the firmware about a six moths ago. This particular preset was created about a month and half ago.
Is it a possibility that it is because currently we are having to unplug the whole sound system ever week. Our auditorium is under renovation currently and we are setting up in our gymnasium every week and tear down every week.
