Chuck iControl Projectpage
as written before, i have started writing a chuck script that mapps the midi-data from my iControl to OSC events. I now have set up a proper project page for the script.

I have recently posted about my chuck-script that generates osc events from my m-audio iControl. Now i have written a Processing-sketch, that visualizes the events. The OSC-Events are parsed using the oscP5.
import oscP5.*;
import netP5.*;
OscP5 oscP5;
int buttons[] = {0,0,0,0,0,0,0,0};
float knobs[] = {0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0};
void setup() {
size(500,500);
frameRate(25);
background( 0 );
oscP5 = new OscP5( this, "239.0.0.1", 3334 );
}
void draw() {
drawControl();
}
void drawControl() {
smooth();
ellipseMode( CORNER );
for (int i = 0; i < 8; i++ ) {
fill( 255 * buttons[i] );
stroke( 255 );
ellipse( 10, 20 + i * 20, 15, 15 );
fill( 0 );
rect( 40, 20 + i * 20, 100, 15 );
noStroke();
fill( 0, 0, 128 );
rect( 41, 21 + i * 20, 99 * knobs[i], 14 );
}
}
void oscEvent( OscMessage m ) {
print( " pattern " + m.addrPattern());
println( " type " + m.typetag());
if (m.addrPattern().equals( "/icontrol/button" )) {
int chan = m.get(0).intValue();
int val = m.get(1).intValue();
buttons[chan] = val;
} else if ( m.addrPattern().equals( "/icontrol/knob")) {
int chan = m.get(0).intValue();
float val = m.get(1).floatValue();
knobs[chan] = val;
}
}

I own a m-audio icontrol and some time ago i started to play with chuck a programming language for making electronic music. today i managed to link them together and use my icontrol to start and stop my chuck programms :-)
next thing i will try is to convert the values from the "endless"-knobs to floats and to pass messages to the sub programms
1 => int device;
MidiIn min;
MidiOut mout;
MidiMsg msg;
