Yesterday while tracking some vocals, and guitars I spent a bit of time working on a map. Actually I quite like doing that, as when you are recording your obviously paying attention to the groove, timing, pitch etc. However you don't have a lot to do with your hands. Yesterday was a good 8 hours session so I was starting to suffer from a bit of ear fatigue as well. This somehow helped actually!
Note: I must find some actual graph paper for doing these types of one off maps.
