midimittr is a simple utility to deliver the experience of low-latency MIDI over Bluetooth LE/USB to iOS Music apps that support MIDI. To achieve this, midimittr is routing the virtual ports of supported applications to Bluetooth and/or the USB Ports. If your favourite application is working with MIDI, it will most likely work with midimittr.

Bluetooth over MIDI is supported in iOS 8+ and a feature of OS X Yosemite 10.10+.

Thank you for this


Simple app that solves a big problem. Latency

With this app and a lightning cable, you can turn your iPad into a really REALLY powerful midi controller with almost zero latency. Great apps like the fugue machine aren't just limited to iPad only apps. I send those signals to Bitwig and get great stuff. Thank you very much for making this free.

Is ok, nothing special

Needs auto reconnect, then it will be perfect!


Love this app. I used it with my DrumPants MIDI over Bluetooth triggers and could control all the music apps I use from my pants! Latency was very good and connects perfectly every time.

One thing though is when I go out of range, I'd like it to automatically reconnect to the Instrument when I come back in range. It's super important when performing to have it reconnect without having to fiddle with the iPad in the middle of a set.
