Beta version of Jazz plugin supports MIDI in

Deprecated, please use Chris Wilson’s WebMIDIAPI Shim

The Jazz plugin is a MIDI plugin that works in all major browsers. Until now, it supported MIDI out only, but today a new version with MIDI in support was released for testing. Currently this beta version is for Windows only. All major browsers are supported. I made an example that shows you how to setup MIDI connections with the Jazz plugin, see: http://abumarkub.net/jazz/

New API in MIDIBridge

Deprecated, please use Chris Wilson’s WebMIDIAPI Shim The new API is an implementation in Java and Javascript of the W3C proposal for MIDI support in browsers by

Jussi Kalliokoski. You can read the proposal here. Besides the API that Jussi proposes, I have also added some extra functionality, notably a Sequencer. The documentation still is very scarce, I will add it bit by bit the coming weeks. Meanwhile the code examples provide useful information on using the new API. All code is available at Github and you can test the code examples online as well: 1. A basic example. code | launch 2. Connects your your computer keyboard to a MIDI output. code | launch 3. Example that lets you select a MIDI input and a MIDI output. code | launch 4. Same example as above, but the MIDI output gets connected directly in Java which results in better playback performance. If your application does a lot of graphical updates on incoming MIDI events, you should use this method. code | launch 5. Select a MIDI file on your local hard drive and play it back on a MIDI output. You can change the instrument as well. code | launch 6. Same example as above, but the MIDI output gets connected directly in Java which results in better playback performance. code | launch 7. Example of how you can send MIDI events generated in Javascript to a MIDI output. code | launch If you come across bugs or issues, or if you have feature requests or other questions, file an
