GarageAcidLab is a Pure Data patch for making algorithmic garage/acid music, like on a 303. You can play it with a midi controller, or buy it for your Android phone.
There is an album of music made using these patches called squeakyshoecore.
These patches started life as an RjDj scene.
You will also need s-abstractions and rjlib.
