Simple Sound Font Synth Host
This is a simple demonstration of how to include a Web MIDI Synth  that uses soundFonts in a Web application.
It can be tried out at
The ResidentSf2Synth used in this demo is a version of the gree sf2synth.js to which I have added an API that includes the Web MIDI API for Output Devices. I have also enhanced the original synth to enable soundFonts to be cached and changed at runtime.
The synth implements standard MIDI controls. The messages that can be sent are declared in its commands and controls attributes.
Issues relating specifically to the ResidentSf2Synth should be raised at the WebMIDISynthHost repository.

 A "Web MIDI Synth" is a software synth that uses the Web Audio API to implement the Output Device interface defined in the Web MIDI API. Web MIDI Synths can be used online independently of browser implementations of the Web MIDI API. Standard Web MIDI Synths can be used interchangeably with the hardware synths supplied by browser implementations of the Web MIDI API.
