GranCloud is new application for the generation of real-time granular synthesis in the SuperCollider programming environment. Although the software was initially programmed for use in the interactive composition Creo, it was implemented as an independent program for use in any computer music project. GranCloud consists of a set of SuperCollider classes representing granular clouds and parameter objects defining control data for the synthesis. The software is very flexible, allowing users to create their own grain synthesis definitions and control parameters. Cloud objects encapsulate all of the control data and methods necessary to render virtually any type of granular synthesis. Parameter objects provide several simple methods for mapping grain parameters to complex changing data sets or to external data sources. GranCloud simplifies the complex task of generating granular synthesis, allowing composers to focus less on technological issues and more on musical considerations during the compositional process.

Rete Mirabile is my new installation piece combining scientific principles with live computer generated music. The title is a Latin term meaning "Wonderful Net," which I use to refer to the highly convoluted network of biological data that drives my installation. The sonification of data, computer modeling of biological processes, kinetic sculptures, and user interactivity are central parts of the installation. The paper is organized as follows: First, brief history of the forerunners that inspired my work is given. This includes a short discussion on how John Cage and David Tudor influenced current artists works, and how those works have influenced my own work. Then I review current installation works that share similarities with my own. Finally, a detailed discussion and analysis of the construction and function concludes the paper.
