BCI - OSC Open Sound Control (OSC) is a universal communications protocol optimized for modern networking to enable connections between computers and other multimedia devices.

EMOTIV’s BCI-OSC enables EMOTIV Brainwear® and Virtual Brainwear® to interface with a wider variety of OSC compatible hardware and software applications. OSC allows you to send mental commands, facial expressions, or performance metrics to an external, network-connected device. The following example details the steps to connect EMOTIV’s BCI-OSC with Max MSP, a visual programming language for music and multimedia.

Step 1: Open BCI

Step 2: Select a profile and connect to a headset (virtual or real)

Step 3: Open BCI-OSC tab and set: Sending mode: Unicast to Self IP: 127.0.0.1 Port: 8000 Data Streams: Select the ones you want to use

Step 4: Click Start

Step 5: Open Max MSP, go to File > Package Manager and install CNMAT Externals

Step 6: Go to https://github.com/Emotiv/opensoundcontrol/tree/develop (need permission to access) and check the table with OSC Address Patterns (see image below)

Step 7: 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.

Step 8: Open Processing and go to Sketch > Import Library… > Add Library , search and install oscP5

Step 9: Open a new File.

Step 10: Import oscP5 to the code and initialize an instance listening to port 12000. Example code (copy and paste in Processing):

import oscP5.; //OSC receiveOscP5
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;
}

Step 11: Click the Play button and watch the graphics change according to Smile. importedValue is associated with the circle radius.

Step 12: Open any example code in File > Examples…

Step 13: Associate importedValue with any float variable from any Library to play around. Be sure to:

Import oscP5:
import oscP5.; //OSC receiveOscP5
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;
}
