I built a fully functional DAW in 3 days using agentic AI tools (Claude Opus 4.5 inside Cursor)… and it actually works.
Open Source!! github.com/mpatti/musio-create
In this video I walk through the app itself (a native macOS DAW) and then show how I “vibe coded” it: MIDI editing, audio recording, tempo control, multi-track routing, and plugin hosting (including running Musio as a hosted plugin). I even experimented with a built-in assistant that can do simple DAW actions (like creating/deleting tracks), plus an AI “fill” tool for adding parts and generating things like key switches / performance shaping—just to explore what’s possible.
I’m not claiming this is ready to ship to millions of users—there’s still testing, polish, and a real beta process needed—but the point is bigger than this one app: the cost + barrier to building serious creative software just changed. A DAW typically takes large teams and millions of dollars… and now one person can prototype something real in under a week.
If you’re technically minded (or just curious about where music software is headed), this is a glimpse into the future.
Tools used: Cursor (agentic IDE) + Claude Opus 4.5
Built with: SwiftUI + Core Audio (macOS)
👇 Question for you:
If you could “build your own DAW,” what feature would you add first?
