The ADJ myDMX 3.0 is a professional-grade software and hardware system designed to control DMX-512 lighting fixtures from a personal computer. It consists of a robust USB hardware dongle interface and sophisticated multi-platform control software, compatible with both Windows and macOS operating systems. This system was specifically engineered to bridge the gap between hardware lighting consoles and computer-based control, offering a more visual, intuitive, and powerful programming environment for lighting designers, mobile DJs, and venue operators.

Upon initial use, the software operates in "Express Mode," which provides 512 live DMX channels and 60 standalone channels for basic scene playback without a computer. However, its full potential is unlocked through a modular upgrade system. Users can purchase additional features, including a 3D visualizer for virtual show design, MIDI mapping for external controller support, an Easy Remote app for smartphone/tablet control, and the ability to expand to multiple DMX universes by stacking additional hardware interfaces. This flexibility allowed the system to scale from simple setups to complex, multi-universe productions.
