Abstract
This article presents practical and artistic contributions to the field of computer music systems based on audio feedback networks. The ideas that oriented the conception of two digital music instruments and examples of their use in the author's music practice are discussed. The article begins with a general conceptualization of feedback systems as well as a brief historical review of its use in experimental music. Later, a more specific contextualization of its application in recent computer music research and artwork is made, and two contributions are presented: the first is a network of cross-modulated sinusoidal oscillators (by frequency modulation), and the second is a network of algorithms for playing and transforming pre-recorded sound samples. In conclusion, examples of the artistic usage of the described systems to the creation of electroacoustic music are discussed.
