Hi Guys,
I found the examples in the discourse very helpful on other topics so I thought I might try and post an example file for those who want a jump start integrating SuperCollider and Processing. It's remarkably easy one you get your bearings:

Just cut and paste both of these into the respective programs and you should have an OSC socket going down!

Supercollider:

/////////
(
SynthDef("rand_osc4", {

arg pick, freq, trig;

var control;
// D-----------F#----------A-------------- is DM here 1,3,5
pick = Dxrand([86,74,62,50,90,78,66,54,93,81,69,57],inf);  

// converts the midi numbers to a frequency
freq = Demand.kr(trig,0,pick).midicps;

a = 0.25; // attack time (in seconds)
d = 1; // decay time
control = EnvGen.ar(Env([0, 0.1, 0], [a,d]), Trig.ar(trig,a+d));

//final output to the channels (is this stereo?)
Out.ar(0, SinOsc.ar(freq) * control);

}).send(s);
)

Processing  (you will need to download the OSC library and put it in the processing folder under Applications)

Ok, I managed to find a Win32 port (link is in the blog post) and tried your example with Processing. It seems that there is indeed OSC communication between SC and Processing, but it keeps giving me these messages:

FAILURE /s_new SynthDef not found
FAILURE /n_set Node not found

I've never tried Supercollider before, so it might easily be something trivial. Any tips

OK, figured out to run the SynthDef (ctrl-return), so now I don't get any error message. But no sound either. There is definitely OSC communication though, and I can get sound with SinOsc commands.

Did you get it running on a Mac or PC? Is there an easy way to print debug messages from SC, i.e. what the values of freq and pick etc are?

Hi Guys,
Nice to see people playing with the code. I used a Mac - actually two macs - one with supercollider and one with processing. Supercollider needs to have its local server booted AND you have to build the Synth before you run the script in processing. See the supercollider tutorial under Help to get started. It's pretty good as far as tutorials go. Here is updated Supercollider code, with test lines at the bottom so you can make sure things are working there first.

Hi guy, i got alredy running processing with Supercollider, Now what i want to do is to connect:

LM35(temp sensor)---> Arduino--->Processing--->SuperCollider

so i can get  a sound signal trigerred by a temperature measure.
So i have already running LM35+ Arduino+Processing, and seperately i have Processing and SC. But i Want all of them running, lets said that when peopleo touch temp sensor (LM35), it sends a value to Processing and process, via OSC send that signal tu Supercollider, So when somebody touch sensor gets sound variations.
Well here i have the code for Lm35+Arduino +Processing separately from the code of Processing+SC:

LM35+ARDUINO+PROCESSING:

//import Serial communication library
import processing.serial.*;

//init variables
Serial commPort;
float tempC;
float tempF;
int yDist;
PFont font12;
PFont font24;
float[] tempHistory = new float[100];

void setup()
{
 //setup fonts for use throughout the application
 font12 = loadFont("AmericanTypewriter-23.vlw");
 font24 = loadFont("AmericanTypewriter-23.vlw");
 
 //set the size of the window
 size(610, 600);
 
 //init serial communication port
 commPort = new Serial(this, "/dev/cu.usbserial-A5002tHf", 9600);
 
 //fill tempHistory with default temps
 for(int index = 0; index<100; index++)
   tempHistory[index] = 0;
}

void draw()
{
 //get the temp from the serial port
 while (commPort.available() > 0)
 {
   tempC = commPort.read();
 
   //refresh the background to clear old data
   background(123);

   //draw the temp rectangle
   colorMode(RGB, 160);  //use color mode sized for fading
   stroke (0);
   rect (100,70,73,213);
   //fade red and blue within the rectangle
   for (int colorIndex = 0; colorIndex <= 160; colorIndex++)
   {
     stroke(160 - colorIndex, 0, colorIndex);
     line(50, colorIndex + 20, 70, colorIndex + 20);
   }
   
   //draw graph
   stroke(0);
   fill(255,255,255);
   rect(200,190,210,210);
   for (int index = 0; index<100; index++)
   {  
     if(index == 99)
       tempHistory[index] = tempC;
     else
       tempHistory[index] = tempHistory[index + 1];
     point(90 + index, 180 - tempHistory[index]);
   }
 
   //write reference values
   fill(0,0,0);
   textFont(font12);
   textAlign(CENTER);
   text("212 F",70, 25);
   text("32 F", 70, 187);
 
   //draw triangle pointer
   yDist = int(160 - (160 * (tempC * 0.01)));
   stroke(0);
   triangle(75, yDist + 20, 85, yDist + 15, 85, yDist + 25);
 
   //write the temp in C and F
   fill(0,0,0);
   textFont(font24);
   textAlign(CENTER);
   text(str(int(tempC)) + " C", 115, 37);
   tempF = ((tempC*9)/5) + 32;
   text(str(int(tempF)) + " F", 115, 65);
 }

Well hope to get recomendationss
R.

Hi, that example is cool, now how can i use it but, get the sound from data from serial, not from the mouse movement. i mean  info from a sensor, any change of sensor read change or trigg the sound from collider
Greetingss
R.
