I have a load of presets that I can’t delete on my H9. They are all the same preset, over 30 of them, and no matter what I do I cannot get rid of them from the H9 using the Control OSX app and bluetooth. The editor will respond if I drag and drop to replace the presets, but not if I choose ‘Delete’. So after dragging and dropping 30 odd times to empty those slots I can ‘save’ the new preset list to the H9. But as soon as I click the pedal icon again the list reverts to how it was before.
