Is there a simple way to make a slider control the rate of any timeline that is running?

I am looking to have a fader that can be used to increase/decrease the running speed of any active timeline, such that as timelines are activated and deactivated, this fader's value will always act as a master rate.

Can this already be done without scripting?

Thanks

  • I haven't been able to throw it in a bench unit to test, but you should be able to stack an action for each timeline in your one slider trigger. You'd be effectively setting the rate for every timeline in your project at the same time. Messy, but effective. 

    If you were scripting, you'd effectively be doing the same thing, so you shouldn't be losing anything by doing it with actions.
