on jobs we use pixlite controllers for controlling lots of addressables and send it artnet out of touchdesigner. no need to involve madmapper as touchdesigner handles all the mapping you could possibly want without adding the latency of piping out to madmapper. if you're just doing hobby projects you can stream serial out of touch via USB to a teensy 3.2 and control (in my experience) around 4000 LEDs at ~60fps. for lasers you should check out the etherdream, simple and works well. servo control you'll need a board but generating the software side in touchdesigner is simple.
