Does anybody knows if there's a browser whith Web MIDI support? ... I've tried the samples on http://webaudio.github.io/web-midi-api/ but they throw me an error that my navigator has not such properties. Im working on google-chrome and firefox. If, there's no browsers that support MIDI, when do u estimate we will have one, maybe in the next 2 years?
According to this posting (dated June 28th 2013), "initial experimental support" for Web MIDI is now available in Chrome Canary.
As of now, there are no browsers that support the Web MIDI API yet. First off, the spec isn't finalized yet and there were a couple of changes made from the original spec (function names and procedures could change anytime).
You can, however, enable your browser to support the API by installing the Jazz plugin and using Chris Wilson's Web MIDI API shim. I have personally tried it and it really works! :)
As of writing this, Web Midi is now available in regular Chrome (not just canary), though it is still an experimental feature, so it must be enabled manually at chrome://flags/#enable-web-midi
try this one, jasmid to play midi files directly on chrome/ff, no plugin needed
One of the authors of the Web MIDI API has created this shim, which enables you to work with the Web MIDI API in today’s browsers:
