transRate
Quantized maximum change-rate distortion Based on a lowpass filter, this module clamps the rate at which the input may change before sending it to the filter. This rate is related to the current amplitude of the signal and the change can be quantized as if it is an amplifier with different transistor-stages, each having a different maximum change-rate. So: mod1: sets the size of the stages, fully clockwise would be 1 stage only->no change. Lowering the control will make the stages smaller and smaller, adding more and more stages and overtones.
