The recording engineer is actually more than one job. It is three jobs at least, the tracking job, the mixing job and the mastering job. I wrote about this in the article: Recording Engineer, Mix Engineer and Mastering Engineer – Oh My. With that in mind, if your project requires all three distinct jobs - most music recording projects will - it might be handy to know how to save things at the end of one job before passing it on to the next engineer, assuming you aren't doing everything yourself. If you are using Pro Tools , you might find this article I just came across to be useful.
It's very short - just a checklist, really. But a very useful one. Check it out here: http://mixmasteredstudios.com/2012/07/save-protools-session-for-mix-engineer/
