Have you ever tried to add interactive music on your website? If you did, you might already know that web browsers don't support low-level MIDI. Not even with HTML5! Jazz-Plugin enables low level MIDI functionality in web-browsers. It allows to play individual notes and control MIDI In/Out devices via Javascript. Jazz-Plugin supports all major browsers in Windows and Mac OS X. You should consider using Jazz-Plugin on your website if you like to publish music lessons, chords and lyrics, online games, or anything else that requires generating on-the-flight music. To install: open the .dmg file and double-click the setup icon.
