Hi, hopefully a quick question.

I'm trying to get a on/off vibrating alert using the Ketai library. I know it should be something along the lines of

vibrate(long[] pattern,int repeat)

I'm not sure what I should be putting in for the pattern; I've try a few things from Android developer sites which look similar but I was struggling get them to work.

This is my code

import ketai.ui.*;

KetaiVibrate vibe;
color backgroundcolor = color(0, 0, 0);

void setup()
{
  orientation(LANDSCAPE);
  textSize(28);
  textAlign(CENTER);
  vibe = new KetaiVibrate(this);
  long[] pattern = {500, 300};
}

void draw()
{
  background(backgroundcolor);
}

void mousePressed()
{
  vibe.vibrate(pattern, -1); 
}


void drawUI()
{
  pushStyle();
  textAlign(LEFT);
  fill(0);
  stroke(255);
  fill(255);
  text("Vibrate", width/2 + 5, 60);
}

Thanks in advance for any help.
