  I’d like to make a square rotating with the basses of a song, with the plug-in Trapcode Sound Keys, i copied in a video this expression:
  minAudio = 0;
  maxAudio = 100;
  minStretch = 90;
  maxStretch = 130;
  audioLev = thisComp.layer(“Sound Keys”).effect(“Sound Keys”)(“Output 1”);
  s = linear(audioLev, minAudio, maxAudio, minStretch, maxStretch);
  [s,s]

  but i think that it works just on the scale, how to fix?
  sorry for the bad english i’m italian.
  Help me please i’m becoming crazy

  Changing the last line to “s” instead of “[s,s]” should do it. Scale is a two-dimensional value (x,y) while rotation is one-dimensional (angle).

  (Actually, deleting the last line would do it as well, since the next to the last line gives the same value.)
