Happy New Year, Peter.
It is definitely one for me. I 'thought' my left slave mixer crashed for like 2 hours. I was just starting a session with a singer that wants to simply sing the song in 'loop play' in Cubase. Perfect. I shut down the slave mixer, loaded an older 1 mixer project, to use just one mixer, and left for an hour. (He will stop and start himself.. ) I come back we chatted and he says goodnight. Now I'm sitting there like, this mixer ain't broke. So I stop and go back the the start, do another reboot, but before I did. I thought, 'I turned the slave off on the master.' I turned it on. Viola!!
I'm logging a lot of years with this mixer(s) not breaking.
So yeah.. Happy New Year!!
