This is a very old article from Sound on Sound magazin from September 2005 – 14 years ago. It is a nice introduction to the value of automation, and the incredible power provided in Logic. Just about everything can be automated – even changing the screen set that you are currently viewing.
It is important to read further to be clear about what Logic Pro X can do (like Track Automation and Region Automation) for just one example.
Comprehensive automation is one of Logic ‘s most powerful facets, allowing micro-management of all the settings in your mix.
