Region Flicker Waveform
All regions have a Flicker Waveform parameter group, which allows you to temporally modulate the patterns within the region.
To enable region flicker, click the check-box just left of the Flicker Waveform group box title. The push-buttons to the right of the group box title allow you to specify sinusoidal, square-wave, triangle-wave, or ramp flicker waveforms. The Amplitude, DC Offset, Phase and Symmetry parameters give you complete control over the flicker waveform, and the Temp. Freq. parameter allows you to specify the frequency of the flicker in Hertz.
