Oscillate Rotation

Author: Michael Natkin & Brian Maffitt

Automatically periodically rotates a layer from side to side. (Use Expression Control angles or sliders for “ from”, “to”, and an expression control slider assigned to “period” for fine control. You can apply these to any layer. Change “linear” to “ease” for smoother interpolation.)

stretch =  linear(audioLev, minAudio, maxAudio, 1.0, maxStretch);
