Hi, I am using 4 snapshots on my HX effects, but I want to use them optionally during the song. Ideally I would have 5 snapshots, but there are only 4 on the HX Effects. I can activate and switch between the snapshots fine, but I can't have them all off - there is always one selected - is there anyway to toggle the snapshots on and off? Have searched the forums, read the manuals, tried different options in the command center but can't find a way to do this. Thanks
