ok, here goes.
Years ago, I'm recording a live African band in 4 separate rooms (including a large ensemble room and concert hall) on 3 floors of studios all set up with radios, video talkback, etc..
I'm the tape op punch master. 24 tracks enabled.
We're doing bass od's. I punch in for ONE 8th note, only FORGOT TO DISENGAGE RECORD ON THE OTHER 23 INPUTS!! So erased 23 instrument inputss for one 8th note!!!!
Fortunately for me, I'm the punch master, and we got the band back in and I punched that 8th note back in. No one could tell (except the keyboard player, who never forgave me).
We were all definitely sweating, especially me!!
OOOOOOOOOOOOPS
