Radio Pyo is now online as a beta experiment. All the compositions are made entirely with Python and Pyo. They mostly have pseudo-random music sections, so technically speaking the chances that you listen to the same song twice are very little :)

I'm contacting the composers in order to make all the sources available in a public repository.

Here's a template with some rules for those who want to submit a composition (for now it's just about sending the script to tiago at acaia.ca):

radiopyo-template.py

#!/usr/bin/env python
# encoding: utf-8
"""
Template for a RadioPyo song (version 1.0).

A RadioPyo song is a musical python script using the python-pyo
module to create the audio processing chain. You can connect to
the radio here : http://radiopyo.acaia.ca/

There is only a few rules:
    1 - It must be a one-page script.
    2 - No soundfile, only synthesis.
    3 - The script must be finite in time, with fade-in and fade-out
        to avoid clicks between pieces. Use the DURATION variable.
