ChucK is a programming language for real-time sound synthesis and music creation. It presents a time-based, concurrent programming model that's precise and expressive (we call this strongly-timed), along with dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OpenSoundControl, HID device, and multi-channel audio.
