MIDI.js is a fantastic library for MIDI sequencing and playback in Javascript. It comes packaged with a soundfont-generator that is unfortuantely a little difficult to get up and running (requires installation of Ruby, Node.js, FluidSynth, Lame, etc.)
This project contains pre-rendered General MIDI soundfonts that can be used immediately with MIDI.js.
