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 or an OSC compatible EMOTIV Brainwear®
2.Choose a training profile 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 https://github.com/Emotiv/opensoundcontrol/tree/master 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;
}
14. 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 importedValue (before void setup);
float importedValue = 0;
Initialize oscP5 (place it inside void setup);
 // Initialize an instance listening to port 12000
    oscP5 = new OscP5(this,8500);
Associate the event with the variable importedValue (place it after void draw); 
void oscEvent(OscMessage theOscMessage) {
    float value = theOscMessage.get(0).floatValue();
   
   importedValue = value;
}
