Hi Ben, a slightly different method than George' solution would be the following:
You connect the Random patch to the value input of the Sample and Hold patch. You connect you LFO to a Pulse patch and result of that pulse patch to the "Sampling" input to the Sampler. The output of the Sampler goes to your sprite width. The pulse patch generates a "1" for exactly one frame and would trigger the Sample and Hold patch just once. find a sample composition attached. Is this what you are looking for? best, Achim Breidenbach Boinx Software
