Remokon Free is an OSC (Open Sound Control) compatible wireless control application. You can develop programs using OSC compatible programming language (i.e. Max, SuperCollider, Processing, etc.). For example, you can play the piano when you push a button and play a drum loop while you push another button.
Remokon Free is a simplified version of Remokon (a paid app) and is designed to be easy-to-use. Therefore it has only three push-buttons and has no configuration. The IP address of a host computer should be "10.0.0.5" and the input port number of a host application should be 57120. The protocol is compatible with Remokon. You can download a sample application from the support site.
