This was my introduction to SAC.
First time running on the brand new system install (not mine, a local club). Nice quiet room, a bunch of senior citizens having an all time ballroom dance.
Until I did something (which I later was able to recreate here) that sent faders flying to +20db as I moved the mouse around the screen. How someone didn't die from a heart attack is beyond me - I know I certainly got blown back the first ... and second time it happened.
Only took months of blaming me, the system, my skills, etc. before it was finally found and fixed.
