A MutaSynth in parameter space: interactive composition through evolution

In this vision paper I will discuss a few questions concerning the use of generative processes in composition and automatic music creation. Why do I do it, and does it really work? I discuss the problems involved, focusing on the use of interactivity, and describe the use of interactive evolution as a way of introducing interactivity in composition. The installation MutaSynth is presented as an implementation of this idea.
