Here’s my first project with Claude Code.

Prompt: "Let's build an application from scratch. Let's make a simple digital synthesizer for music creation. I want us to start with as few controls as possible - maybe just one oscillator!”

Less than five minutes later, it produced most of what you see below. I then prompted two more changes: a cutoff filter, and the ability to adjust these parameters in realtime on a note while it’s held.

Finally, I troubleshooted its performance on mobile. The problem? I had my phone’s side switch set to do not disturb! It should work on both mobile (iOS 26.2 Safari) and desktop (Chrome 143.0.7499.171) browsers.
