A slew rate limiter UGen. Limits the slope of an input signal. The slope is expressed in units per second.
Since the UGen is initialized with the initial value of the input signal, some tricks must be applied to set it to an alternative start value. For example:
input signal
maximum upward slope.
maximum downward slope.
