RAMP FILTER
-----------

Constant-rate linear gliding (ramping) filter.

Rise and fall rates can be specified independently in Volts per Second, where zero means the glider remains stuck, while a higher and higher setting (up to, theorically, infinity) means a faster and faster response.
Negative VSec values are not allowed and will be clipped to zero.

When used with audio signals and setting rise and fall rates identically, the frequency response is pretty similar to an 1-Pole LPF Filter.
