Audio modulators: move with the song

A modulator adds the song's loudness, or a steady wave, on top of a property's keyframes.

Try this

  1. Press play with sound on. Demos 1 to 6 follow the song; Demos 7 to 9 follow a wave.
  2. Click a layer in Demo 2. In Transform, click the wave button beside Position Y.
  3. Drag Amount for how far it moves. Smoothing softens the tail after each hit.
  4. Set Source to Oscillator to move without a song. Shape and Rate set the wave.
