soundmachine.pro / web + desktop

Electronic music production that feels alive, without the gatekeeping, drag, or intimidation.

Fast enough to be playful, capable enough to matter.

Sound Machine is a stripped-back rhythm and arrangement workspace built for immediacy: pulse, orbit, glitch, and drop into the browser the second you are ready to build. Every feature is free and open to everyone.

A direct path from idea to arrangement

Designed for immediacy

Immediate rhythm engine

Start with drums, bass, and arrangement blocks instead of a blank DAW. The interface stays minimal so your first useful idea appears fast.

Visualizer as instrument

The radial visual language idles like music is already running, glitches lightly, and reacts to your cursor. The landing page borrows the app's visual core directly.

One surface, multiple homes

The same full experience runs in the browser and in native desktop builds, so nothing feels like a separate product when you move between web and local installs.

Open with no strings

No trial timer, no feature lock, no sign-up flow. Open the app, press Start, and build. Everything is available on the first load.

Start where you want to work

Browser runtime

Use soundmachine.pro/app for the fastest path into the instrument — no install, no login, all features available immediately.

Open /app

Desktop builds

Prefer working locally? Desktop builds for macOS, Windows, and Linux carry the same full feature set with native file access and offline use.
