Hey friends,
I am building a computer-assisted music composition web environment for creating and sharing algorithmic computer music. This web environment is and will remain free and I'll also provide free tutorials so that anyone can learn how to create algorithmic compositions.
If you want to see a demo (Mozart's musical dice game):

Or if you want to try it yourself:

If you're interested in learning more about algorithmic music, I'm also selling an e-book ($10 usd) to support the development of this software:
