VSXu (VSX Ultra) is an OpenGL-based (hardware-accelerated), modular programming environment with its main purpose to visualize music and create graphic effects in real-time.

Its intention is to bridge the gap between programmer and artist and enabling a creative and inspiring environment to work in for all parties involved.

VSXu is built on a modular plug-in-based architecture so anyone can extend it and or make visualization presets ("visuals" or "states").

VSXu is distributed free of charge with optional paid DLC which deliver extra content.
