quadrant
Quadrant distortion that imposes an offsets to the signal when changing: mod1: direction (signal going up/down) mod2: positive/negative (signal being +/-.... well duh ;) ) Damp control the filter cutoff the filters the offset-generator. Rate linearly limits the change-rate of the offset-generator. So these are non-linear and linear filter-modes that can be combined to your own taste.
