Hi guys, I get the following error wit the "MIDI Out" sketch:

'The constructor Controller is undifined'

Here's the sketch:

import processing.opengl.*;
import promidi.*;

MidiIO midiIO;
MidiOut midiOut;
Bowl[] bowl;

void setup(){
 size(128*5,128*5);
 background(0);
 smooth();

 //get an instance of MidiIO
 midiIO = MidiIO.getInstance(this);
 
 //print a list with all available devices
 midiIO.printDevices();
 
 //open an midiout using the first device and the first channel
 midiOut = midiIO.getMidiOut(0,0);

 bowl = new Bowl[30];
 for(int i = 0;i < bowl.length;i++){
   bowl[i] = new Bowl(i);
 }
 noStroke();
}

void draw(){
 background(0);
 for(int i = 0;i < bowl.length;i++){
   bowl[i].move();
   bowl[i].paint();
 }

}

class Bowl{
 float xSpeed;
 float ySpeed;
 float xPos;
 float yPos;
 Note note;
 color col;
 int myNumber;

 Bowl(int number){
   xSpeed = random(2,20);
   ySpeed = random(2,20);
   note = new Note(0,0,0);
   col = color(
     random(0,255),
     random(0,255),
     random(0,255)
   );
   myNumber = number;
 }

 void move(){
   xPos += xSpeed;
   yPos += ySpeed;
   midiOut.sendController(
     new Controller(0,myNumber,int(xPos/6)+2)
   );
   
   if(xPos > width || xPos < 0){
     xSpeed = -xSpeed;
     xPos += xSpeed;

     playNote();
   }
   if(yPos > width || yPos < 0){
     ySpeed = -ySpeed;
     yPos += ySpeed;
     playNote();
     midiOut.sendProgramChange(
       new ProgramChange(0,myNumber)
     );
   }
 }

 void playNote(){
   note = new Note(int(xPos/5f),int(yPos/10f)+60,int(random(1000)));
   midiOut.sendNote(note);
 }

 void paint(){
   fill(col);
   ellipse(xPos,yPos,20,20);
 }
}


All the other sketches work fine, just this one...
