Right now I've got a small 8x5 music notebook that I've been using to jot down ideas, exercises, and the like so I don't forget them. It's great and handy, but doesn't exactly lend itself to organizing things very well. Has anyone found something like that for iPad? There's a number of notation programs out there, however almost all of them seem to be geared towards actually writing scores. I'm just looking for something I can use to jot down ideas quickly, and better organize my notes, so most of those apps are going to be much more than what I'm actually needing.
