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. This 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. The term ‘mid­ibridge’ includes all Java and Action­script code, and all Javas­cript, HTML and XML files that make this possible.
