Implementing stochastic synthesis for SuperCollider and iPhone

This article reflects on Xenakis' contribution to sound synthesis, and explores practical tools for music making touched by his ideas on stochastic waveform generation. Implementations of the GENDYN algorithm for the SuperCollider audio programming language and in an iPhone app will be discussed. Some technical specifics will be reported without overburdening the exposition, including original directions in computer music research inspired by his ideas. The mass exposure of the iGendyn iPhone app in particular has provided a chance to reach a wider audience.
