Stroke Jitter controls

The Stroke Jitter controls introduces a randomized jitter to the brushstroke. Instead of appearing directly along the stroke, dabs appear randomly outside the brushstroke path. You can also set an Expression setting to further control the Stroke Jitter effect. For more information, see Expression settings.

Audio Expression lets you link the Stroke Jitter effect to audio input from your microphone, or internal audio such as streaming music. The jitter changes in synch with the audio signal.
