  • Wiggle amount controlled by sound keys data

    Hi all,

    I have a wiggle expression driving the values of a slider control which is driving some bezier warp parameters.

    I thought that by placing the slider control on an adjustment layer and then controlling the opacity of the adjustment layer that this might control the slider controls effect. However, of course wiggle expression still fluctuates the slider value regardless of the opacity of the adjustment layer……silly, I know – hey I thought I’d try it!

    Ultimately what I’m after is a way of controlling the wiggle expressions values from some Sound Keys data……..

    Any help would be great! 🙂

    a = thisComp.layer(“sound keys”).effect(“Sound Keys”)(“Output 1”)*3;
    b = thisComp.layer(“sound keys”).effect(“Sound Keys”)(“Output 2”)*6;
    c = thisComp.layer(“sound keys”).effect(“Sound Keys”)(“Output 3”)*10;

    y = a + b + c

    value = y

    wiggle(y,y)

    got it! 🙂

    The line

    value = y

    looks suspicious. I don’t think it hurts anything, but it may not be doing what you expect.
