Dynamically generating MIDI in JavaScript

Of course the HTML5 audio tag doesn't support MIDI. MIDI is (basically) a command set for interacting with tone generators, and beyond that, has nothing to do with making sound. Think of it more like an electronic equivalent to sheet music.<p>Nonetheless, implementing MIDI through javascript would be kind of cool. I'm about 90% done an HTML5 emulation of a Boss DR-110 (warts and all), and while the timing of the audio playback ain't great, I'd be curious to see if better results could be achieved by sending the sequencer data out as MIDI instead.<p>Considering how picky folks get about latency in audio software though, generating MIDI with Javascript seems more useful as a learning tool than an actual music production tool.

An option for browsers that don't support Quicktime is a Java to Javascript bridge that exposes portions of the MIDI framework (could be used as a fallback): <a href="http://mudcube7.blogspot.com/2010/08/dynamic-midi-generation-in-browser.html" rel="nofollow">http://mudcube7.blogspot.com/2010/08/dynamic-midi-generation...</a>

I wrote something vaguely similar, but it relies on App Engine:<p><a href="http://midiserver.appspot.com/" rel="nofollow">http://midiserver.appspot.com/</a> <a href="https://github.com/skybrian/Midi-Server" rel="nofollow">https://github.com/skybrian/Midi-Server</a><p>Agreed that this stuff is way too nonportable.

I've been wanting something to translate old Commodore 128 PLAY strings to MIDI. This might just be the ticket. Thank you, Sergi! I'll try and let you know how this works out!
