I am looking for suggestions for pixel mapping and pattern design software that can drive my system. I have a Teensy 4.1 driving 12 strips of GRBW (warm white) WS2815, totalling right about 3000 leds. OctoWS2811 works great and fast, but I currently am writing patterns in Java, which works but is cumbersome. I am hoping for something a little more creator-friendly, with fast iteration of ideas, perhaps more like the PixelBlaze software. I would be fine attaching a NanoPi or a server to run the software and push data to the Teensy. FastLed does not play well with GRBW. I know there are a lot of large LED projects running on Teensy, how do you do the creative side?
