I would recommend reloading the software on the unit.
- Download H90 Control: H90 Control Downloads
- Boot the pedal while pressing both the SWIRL button and SWIRL Footswitch to enter update mode.
- Connect the pedal to H90 Control via USB to mini B and install/reinstall the latest software.
- Click the hamburger icon at the top left of H90 Control and select dot9 Update Mode
- Follow the onscreen prompts to update to the latest software version.
