Arduino + MIDI Over Bluetooth To iOS, OSX

Developer Matthias Frick – who created the Bluetooth over MIDI app MIDI LE – wants to take the technology to the next level.

Here’s created sketches for the Arduino platform designed to connect USB MIDI devices to OS X and iOS wirelessly over Bluetooth.

Here’s what he has to say about the video demo, embedded above:

I’ll be soon publishing Arduino sketches + the needed items to connect USB Class compliant MIDI Devices to OS X / iOS via MIDI Over Bluetooth. For now it’s just a working prototype – the result of hacking and playing around with Arduino for 24 hours (since I’ve never used Arduino before, I had to face the learning curve first).

Doesn’t do bi-directional communications for now, so you can only control the remote device. Hope to get that in there in the future as well. It also has a few quirks here and there mainly because Apple hasn’t published the MIDI-BLE specifications yet and hides them from the user on iOS and OSX. So this might take a fair amount of time to reverse-engineer.

With the right casing, a battery-pack and a little keyboard this might be a nice item to take on the road for mobile music making.

Hardware used:

  • RedBearLab Blend Micro
  • SparkFun USB Host Shield
  • AKAI MPK Mini
  • iPad


The system is still under development, but Fricke says that he plans to submit the Arduino code to the open source community soon.

  1. This is essentially what Retronyms is crowd-funding but with rows of unnecessary LEDs and a history of not finishing their projects. Would love to see someone else jump in – best of luck!
