Hello,
Sorry to hear you are having issues. Force Mono currently needs to be turned on/off using the pedal UI, it’s not an option in H90 Control. Press the Programs and Routing buttons together to get into the system settings, then choose I/O, and scroll using the Select Knob until you find the “Output Mode” option. This should be “auto” by default, and updating to the latest release should not affect your H90’s outputs.
Could you please provide some more information about your setup?
What I/O are you using on the H90?
Are you using inserts?
Does the issue with only 1 channel outputting audio persist with all Programs?
