Limit effect to y position
on Jul 11, 2006 at 6:15:23 pm

I'm trying to simulate an equalizer using Trapcode Soundkeys in AE7. I have generated the keys and want to animate the y postion of a solid layer masked by another layer. How do i limit the effect to just the y position after linking to the Soundkeys adjustment layer? Is there an expression to do this? Many thanks.

X=position[0];
Y=thisComp.layer("Soundkeys").effect("Soundkeys")("Output 1");

[X,Y]

Great, thanks. Now how do I reverse the effect, right now it is moving top to bottom, I would like it to reverse, bottom to top?

Thanks for your help.

Just use a "-" before the Y position.
