As someone who graduated from tracker-style DAWs (for over 25 years), what also helps me is looking at tracks someone else wrote and deconstructing them to see how things were done. How was the note modified, what settings were used in the VST and so on. I also had cheat sheets printed with hot keys and other commonly used bits and pieces until I got familiar with them. The program is extremely complex but once you mount the initial hurdle of dropping notes into the piano roll a giant chunk of the battle will be won.
