SYMMETRY varies the span of the waveform and is most commonly used for Pulse-Width Modulation (PWM). This is especially useful when SYMMETRY is used as a Modulation Target, as it adds shifting tone color and movement to the sound. The waveform display will dynamically change the waveshape as the slider is moved.
NOTE: For the NOISE waveform only, the SYMMETRY slider acts as a morphing filter that sweeps through four different types of filters. Starting at the minimum setting with lowpass to a notch filter, then to a highpass and finally to bandpass at maximum setting.
