Library to access a Novation Launchpad in a java application. Fork of https://rynr.github.io/launchpad/

Launchpad

This library can be used to access a Novation Launchpad from a java application.

Usage

You can directly use it from maven central:

<dependency>
  <groupId>org.rjung.util</groupId>
  <artifactId>launchpad</artifactId>
  <version>1.0</version>
</dependency>

To send colors the the launchpad, the methods set(pad, color):

launchpad.set(Pad.A4, Color.RED);
launchpad.set(Pad.find(3, 1), Color.GREEN);

To retrieve messages, implement a LaunchpadReceiver and register it to the launchpad instance. The LaunchpadReceiver will now be called always, when a Command is received.

new Launchpad(new LaunchpadHandler() {
    public void recieve(MidiCommand command) {
        System.out.println(command);
    }
});

Example

There's also a rewritten version of the Games of Life in the branch life.

Build it yourself

The build uses maven. You don't need to install anything besides a java 8 development kit (jdk8). Now just run:

./mvn clean package

The build jar can be found in the target-folder.
