I don’t think the standalone smallbatch ever got updated with the ‘finished’ patch in monome_sum. It’s likely only a small job to do so (probably just copying the route.js and led_route.js from sum into smallbatch), but I can’t say it’s on my priorities list right now.
There’s definitely code in monome_sum to allow smallbatch to handle multiple varibright grids, or even a combination of some vari, some non-vari grids.
