MidiWrist turns your Apple Watch into a wireless MIDI controller and provides Siri voice control over MIDI on all iOS devices.

The tactile feel of the digital crown combined with haptic feedback, gives you control over any MIDI synthesizer by touching your wrist, even when you're not looking.

MidiWrist makes no sound on its own.

Any CoreMIDI application or device can be controlled by MidiWrist. This includes Virtual MIDI, Network MIDI, Bluetooth MIDI and Physical MIDI Devices through a supported MIDI hardware interface.

Note that Siri activation with "Hey Siri" might not work on the same device that is running the audio app that you want to control, due to the audio device being used for other purposes.

• Macro control over multiple synth parameters from the Digital Crown
• Remotely Play / Stop / Record / Rewind your DAW from your Watch

Great Concept and Excellent Execution

If you are a dedicated iOS musician, and happen to own an Apple Watch, you must purchase this immediately! I found a bunch of uses for it and the developer keeps adding new features. He’s also been very helpful and this is an example of a situation where you will be very glad you spent what isn’t even that much money.

Very useful

I control my ForScore sheet music app’s backing tracks from my watch. You do have to have the phone with you. The midi routing is done in the app on the phone. There is set up required in the ForScoe app also.
