Launchpad - Processing Library to control Novation Launchpad

This library provides an interface to access novation's launchpad programmatically. It's based on Thomas Jachmanns ruby launchpad gem. LEDs can be lighted and button presses can be listened to. In addition, it includes a wrapper for the Monomic Library as well.

Requirements

Severin Smiths themidibus library
On Mac OS X < Java Update 6 you need Humatics mmj library as well. Yes, go and spend those 3.5 - it's worth it!
obviously a Novation Launchpad ;-)

Installation

Download, unzip and put the extracted launchpad folder into the libraries folder of your processing sketches. Reference and examples are included in the launchpad folder. If needed (only Mac OS X with java Update < 6), install mmj library as described in their documentation.

Usage

Basically, create an instance of the Launchpad class and your're ready to go. This is a simple example that switches on all LEDs (for testing), resets the launchpad again and then lights the grid button at position 4/4 (from top left).

import themidibus.*;
import com.rngtng.launchpad.*;

Launchpad device;

void setup() {
  device = new Launchpad(this);
  noLoop();
}

void draw() {
  device.testLeds();
  delay(1000);
  device.reset();
  delay(1000);
  device.changeGrid( 4, 4, LColor.RED_HIGH + LColor.GREEN_LOW);
}

For Interaction, make sure to include Pressed/Released Listener for grid, the button on the top and scene buttons on the right. This is an interaction example lighting all grid buttons in red when pressed and keeping them lit.

import themidibus.*;
import com.rngtng.launchpad.*;

Launchpad device;

void setup() {
  device = new Launchpad(this);
  noLoop();
}

void draw() {
}

void launchpadGridPressed(int x, int y) {
  device.changeGrid( x, y, LColor.RED_HIGH);
}

void launchpadButtonPressed(int buttonCode) {
  if(buttonCode == LButton.MIXER) exit();
}

For more details, see the examples. Most examples are ported from the ruby and monomic library

Near future plans

add proper Exception/Warning handling
use entities instead of Consts??
add test (how to do this with processing??)
