Thanks for the feedback! The WebAudio plugins support with the faust IDE is indeed the simplest way, however, keep in mind that things like the GUI Builder/exporter with GUI are very young/beta. We will work again on the GUI Builder soon + lots of things need to be done yet... Don't hesitate to contact me if you need help or if you would like to contribute.
