# 🦊 Devalang (CORE) — Compose music with code


Devalang is a tiny domain-specific language (DSL) for music makers, sound designers, and audio hackers.
Compose loops, control samples, render and play audio — all in clean, readable text.

Whether you're building a track, shaping textures, or performing live, Devalang helps you think in rhythms. It’s designed to be simple, expressive, and fast — because your ideas shouldn’t wait.

From studio sketches to live sets, Devalang gives you rhythmic control — with the elegance of code.

> 🚧 Alpha Notice 🚧
>
> Includes synthesis, playback, and rendering features, but is still in early development.
>
> Currently, Devalang CLI is only available for **Windows**.
> Linux and macOS binaries will be added in future releases via cross-platform builds.

## ⏱️ Try it now !


### Try Devalang in your browser


> Have a look at the [Playground](https://playground.devalang.com) to try Devalang directly in your browser

### Try Devalang CLI


```bash
# Install Devalang CLI globally

npm install -g @devaloop/devalang

# Create a new Devalang project

devalang init --name my-project --template minimal
cd my-project
```

Create a new Devalang file `src/index.deva` in the project directory:

```deva
# src/index.deva


group myLead:
    let mySynth = synth sine {
        attack: 0,
        decay: 100,
        sustain: 100,
        release: 100
    }

    mySynth -> note(C4, {
        duration: 400,
        velocity: 0.7,
        glide: true
    })

    mySynth -> note(G4, {
         duration: 600,
         slide: true
    })

# Play the lead


call myLead
```

And the best part ? You can play it directly from the command line:

```bash
# Play the Devalang file

devalang play

# Play the Devalang file with watch mode

devalang play --watch

# LIVE mode (repeat the playback + watch mode)

devalang play --repeat
```

### 🎉 You can now hear your Devalang code in action!
