### 5/5 — Bluetooth MIDI helper

*2026-02-28, version 2.6*

I was beating my head trying to connect an airstep multi to a cme thru6 and them to my Mac. Midimittr sees the devices and connection is as easy as clicking a button. Technology is magic

### 5/5 — Amazing!

*2025-11-19, version 2.6*

Thank you so much for this app! I use it to connect MIDI Wrist Unleashed to Tau DJ on my iPad. As a dance teacher, it’s great to be able to start/ stop music and change tempo without having to go to my iPad!

### 5/5 — Very useful

*2025-05-09, version 2.5.3*

Was able to connect TouchOSC on one iPad with Cubasis on my other iPad. Worked well for mobile music / composing setup via Bluetooth without occupying a USB port. Thanks to the developer :-)

### 5/5 — Awesome

*2025-04-06, version 2.5.3*

Had to give you a 5 star review mate. Does what I need it to and didn’t cost me a penny. Thank you

### 5/5 — midimittr

*2025-03-13, version 2.5.3*

This actually works due to support for the original midi protocol.
This app needs to be considered when using any blue tooth midi device. 
Once this installed it will partner with the newest midi technology allowing for example, 2 keyboards to operate together while delivering midi control data , and program change messages etc to operate simultaneously. This will be sent via a daw or app running on IOS, windows or mac.

### 5/5 — Perfect!

*2024-11-13, version 2.5.3*

Very thankful for this app. Was having major issues getting OP-1F to play nicely with AUM. This app solved my problems instantly.

### 5/5 — Mükemmel

### 5/5 — Great app!

*2024-10-15, version 2.5.3*

Worked perfectly to connect devices with each other. Thank you!

### 1/5 — Running USB version. 'IOS Audio" crashes app on M1 Mac

*2024-08-25, version 2.5.3*

Running USB version. When I launch MIDI LE USB, the midi works to trigger my ipad, but it immediately disables my ipad as an audio input to my mac. When i click 'IOS Audio' under the menubar icon, the app just crashes on my M1 mac. Shame. No manual or instructions.

No manual or response from the developer, who apparently doesn't care. Complete waste of time trying to set up. STAY AWAY.
