From your description you seem to be referring to something similar to this:
https://vimeo.com/85588446I have attached a How-To to give you an idea of my configuration, which is basically 25 spokes, each with 13 pixels and numbered starting from the hub and extending to the tip of each spoke then returning to start the next spoke (i.e. Spoke 1 - at hub #1 at tip #13, Spoke 2 - At hub #14, at tip #26). The Starburst required 3 SSCs and a total of 325 pixels. I also started at the upper most spoke and added spokes, in order, counter clockwise on the upper row, then continued the middle row and finally the lower row.
I have found, that the once configured in this way, the easiest model to use is a simple 13 x 25 matrix, which will have your effects appear to be emanating from the center or tips of the Starburst on effects which go up or down the matrix and rotating around it on sweeps from one side of the matrix to the other.
Here the link to another thread on the Starburst
