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").

The VSXu suite is free software which means it's free from restrictions, free to share and copy, free to adapt / modify and use it any way you like.
