Two dimensional array of osc to max msp

Hi

I'm working on a sequencer based on a 2D cellular automata in processing which uses max msp for audio playback. I've set the processing code up so that it should send a message to max each time a cell on the CA is on. How ever I only get a message in max from "/pt1" in processing. If some one could have a look at my code and point me in the right direction I would be very grateful.

Beads and Arrays

I'm writing a program that triggers a different sound every time a box on screen is clicked. I've managed to load the sounds into an array and draw a box to the screen for each sound in the array. Does anyone one know how I might assign an individual sound to each box so that when the box is clicked a sound is played? The boxes can be dragged around the screen, so the sound must play no matter where on screen the box is located.

sketchPath question

Hello

I'm trying to populate an array of minim audioSnippets from the sketchPath but I'm having difficulty with the syntax, any help is greatly appreciated.

sourcefile = new String [numSamples];

int count = 0;

for (int i = 0; i < listOfFiles.length; i ++){

if (listOfFiles[i].isFile()){

if (listOfFiles[i].getName().endsWith(".mp3")){

sourcefile[count] = listOfFiles[i].getName();

count ++;

}

}

}

try{

for (count = 0; count < numSamples; count ++){

samples[count] = new AudioSnippet(minim, new sketchPath("") + "samples/" + sourcefile[count]);

}

}

catch (Exception e){

println("Exception while attempting to load sample!");

e.printStackTrace();

exit();

}

}
