"Switched-On Monk"

Here's some new cellular automata music I made for fun over my Christmas vacation:

The original MIDI tracks were created by Automatous Monk. I then imported these tracks into and mixed them in GarageBand. I didn't tinker with any of the notes, but did add drum loops to a couple of the tracks and 'fairy dust' such as reverb.

Title: Cellular automata and music

Take computers, mathematics, and the Java Sound API, add in some Java code, and you've got a recipe for creating some uniquely fascinating music. IBM Staff Software Engineer Paul Reiners demonstrates how to implement some basic concepts of algorithmic music composition in the Java language. He presents code examples and resulting MIDI files generated by the Automatous Monk program, which uses the open source jMusic framework to compose music based on mathematical structures called cellular automata.... read more

The Monk now composes Apple GarageBand loops

A new application, GarageBand Loop Generator, has been added to the Automatous Monk suite of applications. GarageBand Loop Generator will generate electric bass-line MIDI files.
