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.

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.

Excellent, wish I knew about this earlier...

Whoa, I can send chord progressions from an MPC Touch to just about any synth on my iPhone/iPad & resample it back into the MPC...That's just the beginning, once you throw Audiobus into the mix you can add effects and record it anywhere you want on ur iPad/Phone... opens up endless possibilities. Insanely great stuff guys, thanks.
