Ok, I think I've about got it. Not so well I can do everything on the fly, but well enough that with some scripting notes I can run a prepared set and sound like I know what I'm doing. I started taking notes on some of the more difficult transitions, which turned into much more detail. Things like times to cut in and out, what bpm I should adjust by, if any, what kind of cut to use. Its still just a guide, all the fine tuning happens by hand, but it makes the job a lot easier. Now when I can do the fine tuning fast enough that I don't need the notes, then skillz will be where they need to be. Still, not bad for about 4 hours work today.
