Creating an 8 segment stereo level meter.

Doing some metering for LED displaying, and would like to represent what will be seen on the controller using jitter. I tried whipping something up using panels, but it became apparent that approach would slow down my patch immensely and apparently isn't very efficient. I imagine this would be fairly simple to do with jitter, but I'm not that well versed. Would the easiest approach be to just use an 8x2 matrix, unpack it, and send the appropriate (setcell) messages to planes representing the color? Or is there a more elegant approach? What about transparency for the non lit cells? Gen solutions are welcome.

The control is a list of 8 values, indicating if an LED should be on (1), or off (0).
