Hi, new user here... and not a very happy one so far. I'm a professional live sound engineer. Part of the job is having canned music to play through the PA, which I was hoping to use my new iPad for. It's looking like this is going to be a problem. What I need is a way to get stuff off of the cloud and onto this device. I need to be able to do it on the fly, and without having to rely on synching with a desktop machine. I always have wifi; an extra computer not so much. I don't care if the solution is Dropbox or iCloud or whatever but I need something that works. Can anyone help?
