This article outlines known issues and workarounds related to the new Windows MIDI Service update.


Microsoft is gradually rolling out a new Windows MIDI Service through Windows updates. While this update introduces improvements to MIDI functionality, it is currently causing issues across ROLI products and other MIDI-based software.


How users may experience these issues:

  • Midi inputs may not be present in standalone apps or DAWs. Restart these for them to be visible.
  • ROLI Airwave Service may not appear as a midi input in ROLI Airwave Player or DAW. Follow the ROLI Airwave Player workaround to fix this.
  • Air Gestures not visible / audible in ROLI Airwave Player but hands do appear. Follow the ROLI Airwave Player workaround to fix this.
  • Midi device may not appear as a selectable device during calibration in ROLI Airwave Player. Follow ROLI Airwave Player workaround to fix this.
  • Device doesn't appear in ROLI Dashboard. Restart ROLI Hardware Driver service and Dashboard for these to appear.
  • Device doesn't appear for registration in ROLI Connect. Restart the ROLI Hardware Driver service for these to appear.


Recommended Workarounds
