This patch is an Lf-noise generator, similar to rand~ (and borrows from the gen.random example), but adds two things– nonlinear ramping modes, and a ramp slope control.
The ramp slope control (called ‘ramp value’) let’s you ‘ramp up’ the slope of interpolation such that the target random value arrives early and holds, creating a stepped component to the waveshape. This is useful if you like to have your parameters glide to a spot, hang out for a while, then glide again to another spot. At the extreme, it turns the waveform into a pure noise step function. It can also be modulated for added wildness.
