Multitouch drum machine

Sound toy demonstrating the use of the Tuio (multitouch) protocol. This application uses the Tongseng (https://github.com/fajran/tongseng) OSX Tuio wrapper for Mac OS X multitouch events along with Apple’s Magic Trackpad. The aim of this application is to emulate a basic drum machine. The Minim sound library (http://code.compartmental.net/tools/minim/) is used to control all sound events. This application uses the Tongseng application is running on port 3333.

This software experiment explores alternate interaction uses of a laptop touchpad. Touchpad allow gestures to be detected by registering multiple finger touches. This software exploits the multiple touch functionality, allowing the user to treat the touchpad as a drum machine. The touchpad is divided into four regions; when touched plays a percussive sound.

The software is built in Processing using the Minim sound library and the TUIO messaging protocol using the Tongseng TUIO wrapper.
