This one is tedious to explain but I can reproduce the issue consistently.
If I turn on the HX Stomp XL and it is in Stomp Footswitch Mode, I can press View and go into Edit Mode.
While in Edit Mode, I can simply touch a footswitch to select any effect assigned to it. If I touch and hold, it will ask if I want to assign to that footswitch. It works for all 6 footswitches (naming 1:bank up, 2:C, 3:D on the top row and 4:bank down, 5:A, 6:B on the bottom row).
If I go back into Stomp Footswitch Mode from Edit Mode, then hit the Mode footswitch and go into Preset Footswitch Mode this is where I can cause the issue. If I press (not touch) to select any preset assigned to footswitches C, D, A, or B (even the preset I’m currently on) and then go back into Stomp Footswitch Mode, and then into Edit Mode, then whatever footswitch I pressed will not work for selecting or holding to assign. So if I pressed 2 of the footswitches those exact 2 won’t work, same if 3, or 4.
I have to turn the HX off and back on and then all footswitches work again in terms of selecting and assigning in Edit Mode. Is this an issue or am I doing something wrong? Can anybody reproduce this? Thanks for any help!
