# Example connection with MaxMSP Once you subscribe to the OSC module, the tab is enabled in BCI. The following example demonstrates a connection of EMOTIV BCI with MaxMSP**,** which is a visual programming language for music and multimedia. 1. Connect a simulated device (create one on EMOTIV Launcher if you don't have. See [Creating a virtual brainwear](https://emotiv.gitbook.io/emotiv-launcher/devices-setting-up-virtual-brainwear-r/creating-a-virtual-brainwear-device)) or an OSC compatible EMOTIV Brainwear® 2. Choose a [training profile](https://emotiv.gitbook.io/emotivbci/training-profiles) to connect to the external device. 3. Select Sending mode: Unicast to Self 4. Set the IP: 127.0.0.1 5. Set the Port: 8000 6. Choose the Data stream you want to connect: Facial expressions, Mental Commands, or Performance Metrics 7. Click Start 8. Open Max MSP, go to File > Package Manager and install CNMAT Externals 9. Go to and check the table with OSC Address Patterns 10. Create (replicate) the nodes below and change OSC-route according to whichever OSC Pattern you wish to address (in the example image, Facial expressions/Smile) - check table in the previous step for the addresses. 11. Open Processing and go to Sketch > Import Library… > Add Library , search and install oscP5 12. Open a new File. 13. Import oscP5 to the code and initialize an instance listening to port 12000. Example code (copy and paste in Processing): |

import oscP5.\*;
//OSC receive
OscP5 oscP5;
// This value is set by the OSC event handler

float importedValue = 0;
float radius;

void setup() {
size(1200,1000);

// Initialize an instance listening to port 12000
oscP5 = new OscP5(this,8500);
}

void draw() {
background (0);
// Scale up imported value
radius = importedValue \* 1000;

// Display circle at location vector
stroke(255);
strokeWeight(2);
fill(255);
ellipse(500,500, radius, radius);
println(radius);

}

void oscEvent(OscMessage theOscMessage) {
float value = theOscMessage.get(0).floatValue();

importedValue = value;
}

Click the Play button and watch the graphics change according to Smile. importedValue is associated with the circle radius. 15\. Open any example code in File > Examples..\ **16.** Associate importedValue with any float variable from any Library to play around. Be sure to: * **Import oscP5;** |

import oscP5.\*;
//OSC receive
OscP5 oscP5;
// This value is set by the OSC event handler

// Initialize an instance listening to port 12000
oscP5 = new OscP5(this,8500);

void oscEvent(OscMessage theOscMessage) {
float value = theOscMessage.get(0).floatValue();

importedValue = value;
}
