Thanks for all the tips on this guys. This simple technique - shape layer with repeater turned out to be everything I needed. So simple and efficient. I did not even have to use the expression, I was not using audio, merely faking it. I just used a wiggle function with a Math.floor() method. Worked beautifully. I always forget about that darn repeater, must remember it, so useful.
And thanks to Chris for the posterizing time tip with audio. did not need it this time round, but I've come up against that before and wish I'd known that then.
cheers

Shape layer. Use a repeater driven by the audio amplitude. Linear expression to set how many units. And for no partial blocks pipe the audio amplitude through a Math.floor for whole units

The matte grid won't do what he wants - I think - because he wants to
quantize the values so that each segment is either on or off, not
partially illuminated. Sounds like something Dan Ebberts could cook up,
but way beyond my ability to execute with expressions.
Hopefully one of the master expressionists on the list can chime in.

If i understand you correctly, i think youre overthinking it. Just put a
grid as a matte above each bar graph blocking out the discrete units. I
dont see why you couldnt do this with audio to keyframe data. Or trapcode
soundkeys

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