Web MIDI Browser is a web browser for browsing Web Apps made with Web MIDI API.

Web MIDI Browser can activate the Bluetooth MIDI functionality which is a new function of iOS 8. Instruments which support Bluetooth MIDI connectivity can be connected to Web Apps by using this App.

Web MIDI API is a new web client API. It's being standardized as a part of HTML5. By utilizing the API, you can build web apps that interact with MIDI instruments, for example, keyboards, DJ controllers and so on.

Originally, MIDI is a physical interface for connecting electric musical instruments to heighten expressiveness of playing music. But now it's used in many ways. Nowadays, web apps are a keystone of great services. If its power comes into the MIDI world, the usability of MIDI is likely to expand. Web MIDI browser can bridge both worlds in iOS.

Doesn't work with Novation Circuit

It doesn't work with the Novation Circuit. Also seems to drain the battery a lot. It used almost 30% of the battery usage for the day, and rest was taken up by the lock screen and various music apps. I removed since it doesn't work for me.

So pain ,


Awesome idea!
It’s insane that this is still not implemented on iOS, but is on every other browser.
Personally, I feel apple is intentionally holding back the web so it can get its 30% cut of apps in the App Store.

This is still the only way to use Web MIDI on iOS, and it’s very much appreciated! Thanks!
