From the site:
Systems music is an idea that explores the following question: What if we could, instead of making music, design systems that generate music for us?
In the 1960s and 70s there was a particularly fruitful period. People like Steve Reich, Terry Riley, Pauline Oliveros, and Brian Eno designed systems that resulted in many landmark works of minimal and ambient music. They worked with the cutting edge technologies of the time: Magnetic tape recorders, loops, and delays.
With Web Audio we can do something Reich, Riley, Oliveros, and Eno could not do all those decades ago: They could only share some of the output of their systems by recording them. We can share the system itself. Thanks to the unique power of the web platform, all we need to do is send a URL.
This is exactly the thing I have been looking for. It’s like the neural synths from Google.
Go take a look.
