I will compile various ways I use the EE as a tool for Musicians. First off and fairly obvious:
1. PDF sheet music - I have pdf sheet, chord chart and grand staff music on a USB stick. Now instead of printing out the paper sheets and flipping them manually, I just put my EE on the music stand and hit the page turn button as I read, play and practice.
I have a recording and mix/master program that is portable on a USB stick. I will post run works and any other apps (drum machine programs, amplifier simulators, signal processors, etc.) that may be useful here in the future.
