This is music that was created using the program FractMus 2000. It uses fractal algorithms to generate pitches, by allowing you to control the type of algorithm, its variable, and musical parameters such as octave range, scale, and rhythmic duration.
You can read more about the program and download it for free at: http://www.gustavodiazjerez.com/?cat=14
I exported the MIDI files from FractMus and loaded them into Reason to assign different instruments to each voice control EQ, panning, etc.
The video is something I created to accompany the music for an electronic music class
