Just prior to show time, I was asked to make a mix adjustment in mix one on the console… with the musician standing next to me, I went to make the requested change only to hit the mix one button and get zero acesss into mix one. The indicator for mix one would not light up and the faders would not shift into my sends on faders. Every other mix worked. Luckily I had the tablet so I was able to make the change there. It was almost like the console didn’t recognize the mix one button at all. I ran the night like that only because I had no choice. By the end of the night, I had managed to shut the console off and restart. The button once again worked
