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. Features: • Standalone MIDI controller for your Apple Watch • Fully configurable on your Watch, no external app is required • Watch face complication to launch the app straight from your watch face • Any number of knobs can be controlled with the Digital Crown • Macro control over multiple MIDI parameters from the Digital Crown • Remotely Play / Stop / Pause / Record / Rewind / Fast Forward your DAW from your Watch • Knobs can be controlled individually or simultaneously • Knobs can be linked to preserve their offsets • Any number of buttons can be toggled by tapping the Watch • Buttons can either be stateful or momentary • Double tap to actuate controls on Apple Watch Series 9, Ultra 2 and later • Buttons and triggers can send a single CC or channel pressure value instead of switching between a minimum and a maximum • Pages can be created with any combination of controls choosing from buttons and knobs • Program changes through the Digital Crown or by tapping the Watch • Transport control over MIDI Machine Control (MMC) or Mackie Control Universal (MCU) • Scrub transport with the Digital Crown • Save / Undo / Redo / Toggle Cycle / Toggle Click / Enter through MCU • XY pad with individual messages for each axis • Stepper panel to step through MIDI values with plus and minus buttons, accelerating as you hold • Motion data (pitch, roll, yaw, acceleration) can be sent in real time • Trigger thresholds for motion data to send discrete messages instead of a continuous stream • Configurable accelerometer range, so a strong movement can be told apart from an ordinary one when you wear the watch somewhere other than your wrist • Optional haptic feedback • Configurable colors for all knobs, buttons and panels • Configurable labels for knobs, buttons and panels • Configurable MIDI channels and MIDI messages (continuous control, program change, channel pressure, note) • Create any number of controller pages you need • Delete and rearrange controller pages • Save your configurations to presets for easy retrieval • MIDI learn for easy controller configuration • Delete and rearrange presets • Connect to other Bluetooth MIDI devices • Low latency and fast response
