 %description
 ChucK is a new (and developing) audio programming language for real-time synthesis, composition, and performance - fully supported on MacOS X, Windows, and Linux. ChucK presents a new time-based, concurrent programming model that's highly precise and expressive (we call this strongly-timed), as well as dynamic control rates, and the ability to add and modify code on-the-fly. 
 In addition, ChucK supports MIDI, OSC, HID device, and multi-channel audio. Furthermore, the language is designed to favor readability and flexibility over raw performance. It's fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis programs, and real-time interactive control.
