Hello everyone, Here is a link to a website that might be of interest to electronic musicians or sound effect engineers. http://harmony.sourceforge.net It's for an open-source program that generates sounds from the movement of the planets, written in JAVA. The synthesis is very basic, but with a little bit of tinkering with it, some interesting sounds and even musical ones are possible. One trick is to transpose the planetary voices to fit into a single octave. Enjoy! Christopher Arthur
