I'm all about AnalogX!!!
Back in the day, when I was a 2nd (and before the net was so prevalent), it was part of my job to provide delay times to the engineer. We had some laminated charts from Lexicon with all of the tempos and different delays printed on them. I was also responsible for calculating offsets for flying parts from one tape machine to the other. I got really good at doing that, and took great pride in the fact that I could fly tracks faster than anybody else at the studio.
Then Pro Tools took over and I forgot all that shit.
