“Modular Synthesizer written in HTML5+Javascript. Realtime sound genearation with javascript.

Currently, testing javascript+flash combination for support non-AudioAPI browsers (Internet Explorer / Opera / Safari). Flash-plugin should be installed on those browsers.

But it is not satisfiable performance. I strongly recommend to access with Firefox or Chrome if you have any problem.

* Safari 6 (Developer Preview) also support WebAudioAPI”
