Hi , my sketch hangs when u press many times "q"

"q" decreases the number of points in the line

import controlP5.*;
ControlP5 controlP5;
int tamanoPunto = 2;
int distance = 1;
float rate1 = 0.02;
Fade myFade;
float time =0;
int FadeAmount = 60 ;
void setup ()
{
size ( 800, 400);
smooth();
background(#1D2124);
myFade = new Fade();
frameRate (25);
mouseX = 10;
// HERE !
controlP5 = new ControlP5(this);
controlP5.addSlider("distance", 0, 100, 0, width/70, height-(height/8), width/4-(width/40), 40).setId(1);
controlP5.addSlider("tamanoPunto", 0, 100, 2, width/4, height-(height/8), width/4-(width/40), 40).setId(2);
controlP5.addSlider("rate1", 0.007, 0.1, 0.02, width/2,height-(height/8), width/4-(width/40), 40).setId(3);
controlP5.addSlider("FadeAmount", 0, 250, width-(width/4), height-(height/8), width/4-(width/40), 40).setId(4);
}
//

point (i+=distance, height* noise(i/100, time));
}
