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.
