My job is coding, my passion is electronic music – so why not combine the two? I'm using Node.js to control my music software, broadcasting its audio signal online. The music mix and style are auto-generated, randomly at first. Listeners provide feedback by clicking "applause!" and "boo!" buttons. The feedback data trains a neural network, which then improves the music. I'll show you how I've built this, then let's try it out together in a live demo!
