    Following the tutorial on using Trapcode Sound Keys given at

    https://www.redgiant.com/tutorial/episode-46-music-visualization-with-trapcode-suite/

    I was trying to enter the expression exactly given in the tutorial (shown below), however, I continue to get the error “Expression result must be of dimension 2, not 1”. I tried to search the Internet and folks mentioned that I should be using square brackets instead of round brackets, but that does not help and changes the error. Any ideas on how to fix this?

    The expression I was trying was:

    a = thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);

    a = thisComp.layer("Sound Keys").effect("Sound Keys")("Output 1");
    b = thisComp.layer("Sound Keys").effect("Sound Keys")("Output 2");
    c = thisComp.layer("Sound Keys").effect("Sound Keys")("Output 3");

    y = a + b + c;

    It looks like you left off the last line:

    value – [0,y]

    Oh my, I feel so embarrassed. This is shown in the tutorial too, but after writing what i did, it started to throw the error and i just did not move forward in the video.

    Thank-you so very much 🙂
