Couldn't think of a more elegant way to title this post. I was working with another engineer the other door on the CS18 and he noticed that if he makes some quick changes in monitor mixes, sometimes they are not captured, so when he goes back to that mix, the faders are back to where they were before the change. Here's roughly what happened. Band playing, engineer notices that a bunch of sends to Mix 3 need to be removed to reflect a change on stage. Engineer hits Mix 3, takes down (quickly) all of the offending sends and then hits Mix 2 to continue to make adjustments elsewhere. Engineer sees grimace on musicians face so goes back to Mix 3 and the sends are still where they were before he took them down. We tested this post gig and found that if all of that took place in less than about a second, then the CS/RM partnership didn't record the change. If it took over a second (roughly) to return to the other Mix, then it did.

Obviously the trick is to dwell a moment before going to a different Mix, but as engineers we often have to do a load of things very quickly and it becomes natural to punch the buttons, move the faders and punch another one.

Anyone else experienced this or similar?
