There are many ways to incorporate generative music into electronic music performance. Since 2012 I have explored methods of integrating SuperCollider instruments into a Ableton Live set. This most recent development is a touch-screen UI built with modern web technologies, controlling SuperCollider patches through a Node.js server (running inside an Electron app). By using experimental Ableton Link support not yet released in SuperCollider, I can synchronize the clocks of rhythmic generative patches from SuperCollider with sounds in an Ableton Live set.
