Connecting multiple animation channels to one slider

[bfx]

Hi there, I'm in the middle of putting this cracking earth rig together.  The sim is running fine, but what I really want to do is bake out the aniamtion of all my peices, and then attach all of them to one slider and delete the dynamics, kind of like a slider controlled Time Warp.  Now I knew this was possible in theory but I'm not getting the results I was looking for.

I thought making a clip was the way to go but I can't seem to get a rig setup where the scene updates in realtime when I adjust the slider.  Anyone done a setup like this before?

make a new time node. Then explicitly connect your animcurves to the new time node (animcurves have a implicit connection to default time if not connected otherwise). There is now just one channel to animate
