Is there a method for laying out a series of recorded audio events?

Not quite sure exactly what you are describing. But if you mean you were jamming over a 12-bar loop and in the process created a bunch of takes on different Lanes then it is pretty simple. On the first (top) Lane grab the Audio Event by the lower right corner and drag it to the right and it will start to show the contents of the next Lane. Keep dragging to the right to reveal successive Lanes.
