Updated my LT to 2.90. I had backed up (saved) my presets, and when I loaded them back in after the update, (they worked) except my volume (foot pedal)/output (big knob) control just stopped working on all of them. I would like to do a complete factory reset, and then reload 2.90, but when I read the instructions to do that, it seems I can't because I don't have a foot switch "9" and above which seems to be required to do a full reset. The Helix Floor has the 9-12 buttons, but the LT only goes to 8. How do I reset the LT to be able to load in 2.90 from scratch again? Is it even possible?
