A lighting controller, control surface with 5 faders and 2 encoders, a USB DMX interface, an ARTNET node, and a standalone DMX generator. The Core-Micro system consists or 4 modules; the logic processor, the control surface, the DMX interface, and the redundant USB-C power supply
A lighting controller, control surface with 5 faders and 2 encoders, a USB DMX interface, an ARTNET node, and a standalone DMX generator. The Core-Micro system consists or 4 modules; the logic processor, the control surface, the DMX interface, and the redundant USB-C power supply. These modules are designed in a way that allows them to be iterated on separetly and allow for a limitless amount of configuration. How do you use Core-Micro? It depends on how YOU need to use it. Core-Micro can be used as a midi controller for On-PC lighting softwares, it can be used in a standalone mode where it…
