I'll try and explain with an example.
Lets say you have an animation of a bouncing ball, straight up and down. But then you also want to move that ball left and right while it's bouncing.
Or, take my XDJ skin for another example. The tonearm moves accross the record as it plays, but I wanted the arm to bob up and down ever so slightly at the same time, to simulate bumps in the record.
Does that make any more sense? Lol, sorry if it doesn't. Here's a diagram too, maybe this will help
> Master Animation Folder
>> Frame 1 (but actually another animation folder)
>> Frame 2 (but actually another animation folder)
>> Frame 3 (but actually another animation folder)
See now? The ability to treat folders as animation frames, so that you can cycle through different animations.
That's the best I can do. If you're still lost, just ignore it. Thanks for your time anyway dude.
Peace, Lance
