I think he wants slow changes. There is basically two types, just slow
variations, or random steps.

The slow variation version is just a lowpassfiltered noise source, if
you vary the lowpass filters frequency, you have more or less of the
quicker movements.

The random step version is a noise source with a sample-and-hold
circuit controled by an LFO. As you vary the frequency of the LFO, you
vary the length of each step.

Both these can use a common noise source, the after-processing is
simple to duplicate.

You DO get noise outputs as a side-effect.

Cheers,
Magnus - contributing to the noise - that must make me a noise generator...
