Hi Adam,
the Snap To Grid iExpression can round continuous values to discrete steps and you can conveniently set the step size. The beauty of the iExpression is that you don't need to go 100% abruptly from one step to the next but can still say "use 10% of the time to smoothly transition from one discrete value to the next one".
More infos here:
Its contained in the movement modifier bundle which is only $9.99
While the name "Snap To Grid" makes it easier to think about it for 2d or 3d position values, you can also make something like Opacity or Rotation snap to certain steps. Here is a tutorial showing how to apply it to rotation in order to make watch hands move in discrete (seconds) steps.
Cheers, Mathias

I need to create a VU style meter with 6 discrete levels. I looked at the Audio Spectrum and Audio Waveform effects, but =20 neither of those come close. I searched Goole and found a few examples that use the Audio =20 Amplitude assistant, but that just wiggles the matte which creates =20 thin slivers of meter instead of discrete chunks. Is there a way to posterise to absolute values the scale/volume or =20 whatever property would be needed to control the visibility of the =20 matted layer?
