That being said, it isn't beyond the pale to learn the basics and get yourself up and running fairly quickly. I had to go to school to learn how to use it (before all these damn YouTube tutorials made school obsolete!). Pro Tools is definitely not for the faint of heart and isn't necessarily an app you can just pick up and go with. You can lay down up to 128 tracks per session, with 32 inputs and over 60 plugins, and you can create an unlimited number of sessions. It can be used to record, mix, master, and much, much more.
Pro Tools, by Avid, is one of the most popular music editing apps in the industry.
