Page 8: Activity Parameter
Activity parameter Move the sensor in any direction. The parameter value depends on the velocity. To solo the activity parameter by pushing the SOMI 1 hub encoder button, make fast circular movements. Tilt Angle parameters Tilt the sensor around the X, Y or Z axis (left graphic). The parameter value depends on the ankle (right graphic: X showing to the top=highest sensor value of X Axis, red dot=LED on sensor as reference).
Page 9: Acceleration Parameters
Acceleration parameters Accelerate the sensor along the X, Y or Z axis in the positive direction. If the sensor is not moved or moved in the negative direction of an axis (given the parameter is not inverted), the parameter value remains at 0. With a scale factor of 1.0, the maximum value corresponds to 4G 4x earth gravity).
Page 10: Battery
Note: The middle position of the Tilt Z movement parameter depends on the direction of the sensor and is set during automatic calibration. The LED of the motion sensor corresponds to the middle position of Tilt Z. Note: It’ s recommended to always wear the motion sensors with the LED pointing to the right direction.
Page 11: Usb Midi
The conversion of the movement data received by the sensors into MIDI data depends on the current settings, which can be independently customized for each movement parameter and MIDI message type. For example, one can select a desired movement parameter, which should be used as input to control a specific Control Change Controller.

corresponding USB cable to the USB MIDI device port of your hardware instrument before powering on the SOMI 1 Hub. Afterwards use a USB C power adapter to power the SOMI 1 Hub via its USB MIDI device port. Note: Many MIDI hardware devices offer both, a USB MIDI port and DIN MIDI port. In this case we recommend to use the USB MIDI port due to higher data transfer rate.
Page 13: Technical Specification
To address this problem, SOMI 1 allows soloing a specific Control Change Controller for ease of mapping, which omits all MIDI messages except the soloed controller. A specific controller can either be externally soloed via the SOMI 1 Editor (explained in SOMI 1 Settings Editor section) or directly via the push encoder on the SOMI 1 Hub using real-time analysis of sensor data.

4.2 SOMI 1 Editor for Ableton Live Max for Live Device) For native integration with Ableton Live, SOMI 1 comes with a dedicated Max for Live device allowing customization of SOMI 1 settings in real-time. The different settings can even be automated within Live’s arrangement to create different kinds of dynamic presets in a project.

The gray circle in the SOMI 1 Max device will turn yellow indicating that a MIDI connection between SOMI 1 and Live has been established and SOMI 1 can be now configured via the Max device. Note: You can also arm the MIDI track in Live to enable a connection between Live and SOMI 1.
Page 20 MIDI Settings Global Settings Note: You can hover the mouse over the different UI elements of the SOMI 1 Editor for Live to get more detailed information. Note: Currently shown settings are only updated on the SOMI 1 Hub by clicking the Apply button.
Page 21 Notes: In comparison to Control Change settings, the Note settings are unique for each sensor. Thus the currently shown settings are independent of the selected movement parameters. Furthermore, two movement parameters are required as input. One to distinguish if a note is currently played (i.e. Note On / Off) and another one corresponding to the note pitch.
Page 22: Using Live's Midi Learn Functionality
Using Live’s MIDI Learn Functionality Live’s builtin MIDI learn functionality allows mapping of MIDI Control Change Controllers to one or sound parameters and macros. Typically, one selects the desired sound parameter and changes the value of a Control Change Controller to create a new mapping.

Select the firmware Zip archive and click the Update button below. Wait until the update has finished (max. 1 minute). Afterwards the hub will automatically reboot in normal mode. Note: Only our signed firmware can be used with SOMI 1. If you update the hub with another firmware, the hub will simply fall back to the previous version.
