Creating RjDj Scenes

RjDj has been around since 2008, and the process of creating RjDj scenes has been documented elsewhere (more than once), but only for iOS devices. The appearance of the Android ScenePlayer has introduced just enough additional considerations to merit yet another RjDj tutorial.

The original RjDj app is available for free from the App Store. The Android ScenePlayer is available from the Android Market, and it is also one of the sample projects that come with the Android branch of libpd. Figure 3-2 shows the Android version playing Atsuke, a scene by Frank Barknecht that he generously made available for distribution with libpd. Some elements of the user interface are obvious, such as the microphone gain slider and the transport buttons. Less obviously, the square image above the microphone slider serves a dual purpose. It visually represents the current scene, but it also receives touch events that are passed on to the Pd patch at the heart of the scene.
