Products: Firmware v6.4x

Firmware is a kind of operating system software that runs on microcontrollers (tiny computers) such as used in the Wi-microDig. It handles the capture of analog signals, communication with digital (I2C) sensors, their translation into MIDI messages and communication with I-CubeX software, in both standalone mode as well as host mode. It adds intelligence to the digitizer hardware in the form of the features described below. Starting with digitizers that use version 5.0 of the I-CubeX firmware, the digitizers' firmware can be updated with newer firmware versions. For information about other (older/newer) versions of the I-CubeX firmware please visit the support resources.

Standalone mode allows you to operate without further processing of sensor data on a computer. Configure the Wi-microDig's new standalone mode features released in firmware v6.4x with EditorX v8.1x and it will remember the settings after power down.

Host mode configurations are edited with Link or SensePlay. For more sensor mapping complexity, use the digitizer with the ioCube Touchdesigner node, openFrameworks addon, iCube, oCube or Pd external, and apply almost any signal processing algorithm you like.

Firmware v6.4x is available for Wi-microDigs programmed with firmware v6.1 or greater. To upgrade your Wi-microDig to firmware v6.4x click the "check firmware" button in Connect (v1.5 or higher, only on MacOS for now) or, if you're on Windows, run FirmwareX v6.4x. Access the new features with EditorX v8.1x.

Upgrading your firmware is fully guaranteed. If after performing the upgrade your digitizer still has the same firmware version (ie. it wasn't upgraded) or became unresponsive, send us the digitizer as per the return instructions. We will upgrade the unit and send it back to you for free !


New in v6.41

  • Bluetooth PIN or passcode change to "0000" which makes it far easier to set up the Bluetooth connection on MacOS while also allowing easy setup on Windows.
  • LED control. Turn on/off the MIDI in/out and power LEDs to save power and for less visible presence of the Wi-microDig on stage or in an installation.

New in v6.40

  • Solo feature: output the data from only one (virtual) sensor input.
  • MIDI output range configuration.
  • Map to the pitch, ie. note number, of a NoteOn message.
  • Improved magnitude method for Magnetic3D sensor.
  • Improved compatibility with other I-CubeX software.
  • Faster and more reliable connection setup due to improved handling of Bluetooth pairing. On MacOS no pairing code is needed. On Windows, use pairing code "0" (zero).
  • Disabled due to memory limitations: support for Moist3D sensor, support for any actuators. Revert back to an earlier firmware version if these features are needed.

Example of the virtual input feature: You can map the pitch of an Orient3D sensor placed on the back of a hand to a Pitch Bend message but map the roll of that same Orient3D sensor such that it triggers a Note On when rotating the wrist left to eg. 45 degrees and a Note Off when rotating right to 45 degrees.

Released in previous versions

  • Firmware versioning with 4 digits and build date. As a result, version 6.32x, v6.31x and v6.30x are all the same as v6.3 and will show in Connect (as of Connect v1.5) as v6.300.
  • Improved signal processing for HotSpot2D, Magnetic3D and MoveAround I2C digital sensors.
  • Expanded feature list for FeelVibe and SeeRGB I2C digital actuators.
  • Disabled due to memory limitations: support for MoveAlong sensor, support for pulse width modulation output (PWM) to control RC servos, mapping sensor input(s) to an actuator output. Revert back to v6.32 if any of these features are needed.
  • Virtual inputs for digital (I2C) sensors, allowing the separate mapping of each parameter of an I2C sensor.
  • HotSpot2D support.
  • More Orient3D methods.
  • Support for I2C actuators (SeeRGB, FeelVibe).
  • Support for binary (on/off) actuators (may require re-pinning the actuator plug).
  • Support for pulse width modulation output (PWM) to control RC servos (may require re-pinning the actuator plug).
  • Map (multiple) sensor input(s) to an actuator output: trigger/dim LEDs, control servos or any other device connected to the actuator outputs in standalone mode directly with (analog or digital) sensors; no need for software on a computer to map inputs to outputs.
  • Convert signals varying around a center value to a value from zero: useful for eg. GForce3D, BioVolt.
  • Measure time between or frequency of signal peaks or each signal peak and its reset threshold: eg. measure heartbeat BPM with a BioVolt, time between taps on a Touch sensor, frequency of jabs with a GForce3D sensor.
  • Use digital (I2C) sensors such as the Orient3D in standalone mode.
  • More efficient protocol for digital (I2C) sensors in host mode.
  • Use multiple digital (I2C) sensors on one Wi-microDig.
  • Various other communication protocol and signal processing improvements.
  • Mapping of sensor values to any MIDI channel voice type message ie. note-on/off, key-pressure, control-change, program-change, after-touch (all 7 bit resolution) or pitch-bend (10 bit resolution). MIDI running status can be turned on or off.
  • Sensor data processing: inversion (increasing sensor values result in decreasing MIDI data values), thresholds (the sensor values within the specified range are offset and scaled to the MIDI data output range), zooming (set the sensitivity of an input to a specific voltage range), time averaging (reduce noise by averaging over up to 16 sensor values), differentiation (output only the difference between two successive sensor values), peak/dip detection (detect the largest/smallest value of up to 16 sensor values and output that or a preset value), noise gate (output only when the sensor value changes more than a user-set difference from its current value).
  • Gesture recognition: gesture onset detection (through peak or dip detection mapped to e.g. note-on event with velocity value corresponding to peak or dip value), post-onset processing (continuous averaging and/or differentiation, mapped to e.g. after-touch or pitch-bend messages), gesture end detection (sensor value above/below threshold, mapped to e.g. note-off event).
  • Factory reset option: allows you to return all digitizer settings to its original settings when it was first shipped to you.


The digitizer MIDI communication as implemented by the firmware is described in the USB-microDig firmware reference documentation.
