Simple live synth for my phone

So i used mobile.processing for the first time last night. Great stuff. Made a quick and easy live synth for my phone. It's relatively responsive, considering...

Sketch has been tested and working on a Sony Ericsson K610i

EDIT: fixed up the code (from pasting into HTML), thanks Benoch for pointing that one out!

import processing.sound.*;
int keyvalue = 0;
int[] pitches = {
57, 59, 60, 62, 64, 65, 67, 69, 71};
void draw() {
}
void keyPressed() {
if(key >= '1' && key <= '9') {
keyvalue = key - '1';
keyvalue = pitches[keyvalue];
Sound.playTone(keyvalue, 100, 100);
}
}
