This project provides a bi-directional midibridge that enables Flash or Javascript apps to send midi events to, and to receive midi events from the midi system of your computer.┬áThis means for instance that you can control a Flash or Javascript app via your midi controller, and vice versa that can control a midi device from Flash.┬áThe term ‘midibridge’ includes all Java and Actionscript code, and all Javascript, HTML and XML files that make this possible.
