# Awesome OSC [![Awesome](https://awesome.re/badge.svg)](https://awesome.re)

> A curated list of Open Sound Control (OSC) resources, tools, libraries, and implementations

OSC is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. It enables real-time control and data exchange across networks with high precision.

- **[Lemur](https://www.midikinetics.com/lemur/)** - *Legacy*  
  Multitouch OSC/MIDI controller on iOS. Still widely used but maintenance status is limited.

## Debugging & Utilities

- **[Protokol](https://hexler.net/protokol)** - *Active / Free*  
  Essential debugging tool. Lightweight utility to monitor incoming OSC and MIDI traffic in real-time.

- **[Packet Sender](https://packetsender.com/)** - *Active / Open Source*  
  Network testing tool for manually sending UDP/TCP packets. Great for testing OSC connectivity.

## Game Engines & Creative Coding

### Unreal Engine

- **[UE-OSC](https://github.com/monsieurgustav/UE-OSC)** - Community alternative with additional features

### Unity

- **[OSC Jack](https://github.com/keijiro/OscJack)** - *Active*  
  Lightweight, high-performance OSC implementation for Unity (C#). Gold standard for Unity OSC.
- **[extOSC](https://assetstore.unity.com/packages/tools/input-management/extosc-open-sound-control-72005)** - *Active / Paid*  
  Robust, full-featured asset widely used in professional installations.

### Godot

- **[GodOSC](https://github.com/afarra6/godOSC)** - *Active*  
  GDScript implementation providing OSC send/receive via nodes for Godot 4.x.
- **[GodOSC (Asset Library)](https://godotengine.org/asset-library/asset/2538)** - Official asset library entry

### Other Platforms

- **[Max/MSP](https://cycling74.com/products/max)** - First-class OSC citizen via built-in objects
- **[Pure Data](https://puredata.info/)** - Native OSC support via bundled externals
- **Processing** - See [OpenSoundControl.org implementations](https://opensoundcontrol.stanford.edu/implementations.html)
- **[TouchDesigner](https://derivative.ca/)** - Built-in OSC support for creative coding
- **[openFrameworks](https://openframeworks.cc/)** - Multiple OSC addon implementations available

## Audio & Music Software

### DAWs with Native OSC Support

- **[REAPER](https://www.reaper.fm/sdk/osc/osc.php)** - *Active*  
  Deepest native OSC support of any DAW. Fully customizable `.ReaperOSC` control surface files.

- **[Ableton Live - Connection Kit](https://www.ableton.com/en/packs/connection-kit/)** - *Active / Free*  
  Official Max for Live pack with "OSC Send" and "OSC Receive" devices.

- **[Bitwig Studio - Mossgrabers Scripts](http://www.mossgrabers.de/software/Bitwig/Bitwig.html)** - *Active*  
  Community standard for advanced controller scripts, including generic "Open Sound Control" extension.

- **Cubase** - Native OSC control surface support
- **Unify** - Built-in OSC control capabilities

## Code Libraries

### Python

- **[python-osc](https://pypi.org/project/python-osc/)** - *Active*  
  Modern standard for Python OSC. Supports UDP/TCP with threading/forking server examples. Use this instead of legacy pyOSC.

### JavaScript / TypeScript

- **[osc.js](https://github.com/colinbdclark/osc.js/)** - *Active*  
  Works in both browser (via WebSocket) and Node.js (via UDP/Serial). Highly maintained and feature-complete.
- **[node-osc](https://github.com/MylesBorins/node-osc)** - *Active*  
  Simpler alternative specifically for Node.js users.

### C / C++

- **[oscpack](https://github.com/rossbencina/oscpack)** - *Stable*  
  Classic C++ library by Ross Bencina. Rock solid and widely used. Rarely updated because it "just works."
- **[liblo](https://liblo.sourceforge.net/)** - *Stable*  
  Standard C library. Lightweight and POSIX-compliant.

### Other Languages

- **Java** - Multiple implementations available (see OpenSoundControl.org)
