MidiWrist Unleashed turns your Apple Watch into a standalone MIDI controller that directly connects to any advertised Bluetooth LE MIDI device, without the need of your iPhone or any other proxy. The tactile feel of the digital crown combined with haptic feedback, gives you control over any MIDI device by touching your wrist, even when you're not looking. MidiWrist Unleashed makes no sound on its own and can't advertise itself as a Bluetooth LE MIDI device. NOTE: The reliability of Bluetooth LE MIDI support in hardware devices varies. MidiWrist Unleashed was tested with iPhone, iPad, Mac and CME WIDI devices. We can't guarantee the connection stability nor MIDI message latency with other devices. IMPORTANT: MidiWrist Unleashed can only connect to Bluetooth MIDI devices, and doesn't support Siri commands. If you need to connect to other MIDI devices or use the Siri features, the original MidiWrist app is still available with those features.
