Ramping a wiggle up and down

I'm trying to figure out how to make a wiggle expression ramp up and down between its values, rather than jump to them..I know this has been adressed before, but I can't remember the solution..

Thanks
Alex

I'm not entirely sure what you mean by "ramp up and down....rather than jump", but the easiest way to vary the amount of wiggle is to use an animated Slider Control effect.
wiggle(1,effect("Slider Control")("Slider"));

Thanks Paul

That is a good idea, but what I'm thinking of is more of a change in the "ease" or "curve" of the wiggle. i.e I would like to make the movement between the wiggle values smoother, sort of as an ease in and/or ease out....

Thanks
Alex

You could try using the old "The Wiggler" palette instead of a wiggle expression. Then you'd be able to apply things like an Easy Ease to the resulting keyframes. Also, you could try using a smooth() expression or The Smoother palette on those keyframes.

The 3rd and 4th parameters in the wiggle expression, octaves and amp_mult are only useful for making a wiggle more jagged, so that won't help in this case.
