"On-the-fly Programming: Using Code as an Expressive Musical Instrument"

On-the-fly programming is a style of programming in which the programmer/performer/composer augments and modifies the program while it is running, without stopping or restarting, in order to assert expressive, programmable control at runtime. Because of the fundamental powers of programming languages, we believe the technical and aesthetic aspects of on-the-fly programming are worth exploring. In this paper, we present a formalized framework for on-the-fly programming, based on the ChucK synthesis language, which supports a truly concurrent audio programming model with sample-synchronous timing, and a highly on-the-fly style of programming. We first provide a well-defined notion of on-thefly programming. We then address four fundamental issues that confront the on-the-fly programmer: timing, modularity, conciseness, and flexibility. Using the features and properties of ChucK, we show how it solves many of these issues. In this new model, we show that (1) concurrency provides natural m...
