extOSC - Open Sound Control Protocol for Unity

Created by iam1337

⚙ Build and Release openupm semantic-release: angular

Table of Contents


extOSC (Open Sound Control Protocol) is a tool dedicated to simplify creation of applications with OSC protocol usage in Unity (Unity3d). Supported platforms are PC, Mac and Linux / iOS / tvOS / Android / Universal Windows Platform (UWP) and other.

Also extOSC is available on the Unity Asset Store for free.


  • OSC with coding
    Massive implementation of methods, utils, and other for simple operations with OSС through code.
  • OSC without coding
    With extOSC components you can easily implement basic program logic in your application without coding. Components for basic functions: sending, receiving, mapping.
  • OSC Console
    New separated console for tracking sending and receiving OSC packages: Video.
  • OSC Debug
    New easy to use tool for debugging sending and receiving OSC packages: Video.
  • Map OSC packages
    OSCMapping allows you to map float values: Video.
  • UI
    Four new UI-components for easy creation of remote control apps with OSC-protocols: Video.
  • Addresses with masks support
    You can bind addresses with mask (for instance: "/lights/*/value").
  • Auto pack bundle
    extOSC will bundle your packages for optimisation purposes.

And also:

  • Every data type support (include Array and MIDI)
  • Compatible with OS X, Windows, iOS & Android, Windows Store (Hololens and Hololens 2)
  • Tested with TouchOSC, VVOpenSource, OpenFrameworks and others frameworks and applications
  • Examples

And much more


Old school

Just copy the Assets/extOSC folder into your Assets directory within your Unity project, or download latest extOSC.unitypackage.


Via openupm-cli:

openupm add com.iam1337.extosc

Or if you don't have it, add the scoped registry to manifest.json with the desired dependency semantic version:

"scopedRegistries": [
		"name": "",
		"url": "",
		"scopes": [
"dependencies": {
	"com.iam1337.extosc": "1.19.7"

Package Manager

Project supports Unity Package Manager. To install the project as a Git package do the following:

  1. In Unity, open Window > Package Manager.
  2. Press the + button, choose "Add package from git URL..."
  3. Enter "" and press Add.


Create OSC Transmitter

// Creating a transmitter.
var transmitter = gameObject.AddComponent<OSCTransmitter>();

// Set remote host address.
transmitter.RemoteHost = "";    

// Set remote port;
transmitter.RemotePort = 7001;         

Or you can simple create OSCTransmitter component in Unity editor, or use Create/extOSC/OSC Manager in Hierarchy window.

Send OSCMessage

// Create message
var message = new OSCMessage("/message/address");

// Populate values.
message.AddValue(OSCValue.String("Hello, world!"));

// Send message

Or you can use any extOSC/Transmitter components.

Create OSC Receiver

// Creating a receiver.
var receiver = gameObject.AddComponent<OSCReceiver>(); 

// Set local port.
receiver.LocalPort = 7001;            

Or you can simple create OSCReceiver component in Unity editor, or use Create/extOSC/OSC Manager in Hierarchy window.

Receive OSCMessage

Bind method to special address. In address argument you can use masks like: "/message/*"

// Bind "MessageReceived" method to special address.
receiver.Bind("/message/address", MessageReceived);     

Method realization:

protected void MessageReceived(OSCMessage message)
	// Any code...

Or you can use any extOSC/Receiver components.

Get value from OSCMessage

You have two ways to get the value from the message.

var value = message.Values[0].FloatValue;
// Any code...


if (message.ToFloat(out var value))  
	// Any code...

Other examples you can find in Examples folder.
