To derive a smooth random function you could route the Pink Noise
generator through one of the Lag Processors. A smooth random wave is
useful in small amounts to add a degree of natural variation to timbre when
routed to filter cutoff. Normal pink noise is low pass filtered audio
frequency noise with a 3 dB/octave slope to give equal energy per octave.
XK-6 pink noise is actually more like very low frequency filtered noise, but
it is perfect for use as a random control source.

The Quantizer can generate interesting whole-tone scales when envelope
generators or LFOs are routed to the input. The quantizer turns a smoothly
changing input signal into a series of steps. By routing the output of the
quantizer to Pitch and adjusting the PatchCord amounts, you can control
both the number of steps and the pitch interval of each step.

The input PatchCord amount controls how many steps will be generated.
With a sawtooth wave (LFO+) feeding the input and the PatchCord amount
set to 100%, sixteen steps are generated. The output PatchCord amount
controls the size (or interval) of the steps.
Try setting up the following patch exactly as shown below using your
favorite preset as a starting point.
