The fact that I have to spent lots of time on the web to find a way to delete a preset!?...after spending a LOT of time trying to find a delete function (or a way to delete) on both the HX stomp unit and HX Edit software....with negative results warranties returning this thing. Time should be spend making music not combining insurmountable color blocks and sliders on a screen, off course IMHO. I am sure FX edit-gurus will be delighted, but not a normal musician (pro or otherwise) The irony is, I was expecting to find at least already made presets for the songs (famous pink floyd songs) that I need effects for but there in almost nothing and the ones that are available are just terrible. The presets for bass that come with the unit are completely useless and exaggerated. Good luck pulling up any of these presets on a sound check at any venue. BTW there is no "clear All Blocks" option on the right click menu on HX Edit..the options are: "Copy, rename, import, export" I would have tried clear all blocks and saved time if I saw it!
