Csound is a musical programming language with a very long history, with roots in the origins of computer music. It is still being maintained by an active community and despite its age, is still one of the most powerful tools for sound processing and synthesis. CsoundQt hopes to bring the power of Csound to a larger group of people, by reducing Csound's intial learning curve, and by giving users more immediate control of their sound. It hopes to be both a simple tool for the beginner, as well as a powerful tool for experienced users.
