This sets the number of ruffles. Ruffles are essentially wavy ripples, and they're an optional feature of the Bend effect. The Bend effect consists of three LFOs (Low Frequency Oscillators), which interact to change the pot's radius, as follows:
| LFO | Function |
|---|---|
| Bend | This LFO varies the radius periodically with vertical position; by itself it's identical to Ripples. |
| Pole | This LFO varies the radius periodically with angle, similarly to Scallops; in combination with the Bend LFO, it creates honeycomb-like effects. |
| Ruffle | This LFO also varies with angle, but instead of changing the radius, it changes the phase of the Bend LFO. This produces wavy ripples, also known as ruffles. |
You can have poles without ruffles, or ruffles without poles, but the Pole and Ruffle LFOs both depend on the Bend LFO. To enable ruffles, the Bends, Bend Depth, Ruffles, and Ruffle Depth properties must all be non-zero.
