Bluetooth MIDI helper

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

Amazing!

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!

Very useful

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 :-)

Awesome

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

midimittr

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.
