## What is Web MIDI Browser?

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.

### 1/5 — Broken on Latest iPhone

*2026-06-27*

(on iPhone 17pro max)
Opening the settings menu crashes the app. I want to use this to update my KO2 using my phone, but loading the TE update utility webpage crashes the app. 

I wish this worked so badly! Could be really cool.

### 5/5 — Works great

*2026-02-28*

Works to allow me to connect my MIDI for controllers to my iPad to use browser based configuration. 

World be nice if it had options like configuring a start page or bookmarks, but it works and I’m grateful there’s an iPad option.

### 2/5 — It’s a start

*2025-06-11*

I was hoping to use EP-133 sample tool. It crashes however as soon as connected. Waiting for the fix and many thanks for trying

### 5/5 — WebMidi works

*2022-06-03*

It auto connected to my external synth . Send and receive MIDI worked.

### 3/5 — Really useful tool

*2022-01-09*

Needs work tho. Starting to crash when switching apps on latest iOS. Desperately needs a bugfix.

### 1/5 — Broken

*2021-06-30*

API has changed, no longer works as expected :-(

### 4/5 — Awesome!

*2021-05-29*

Perfect to use my old iPad to a midi controler 👍 I just miss an offline mode, to use it even without network 😕 Is it open-source? Thanks a lot for this application 🙇‍♂️

### 1/5 — No longer working, needs updating

*2021-01-05*

This is a much needed app, but sadly no longer works in 2021.
If developer could fix it, I will give 5 stars.

### 5/5 — It actually works

*2020-12-29*

Enable SysEx in settings and it work like a charm.  Updating a 16n works at least

### 1/5 — Does Not Work. At All.

*2019-10-18*

Web midi must have changed or something. This app will not give you access to web midi at all. 3 years old, this app is abandon-ware.
