Yea I thought of that, just sucks to have to waste a preset for that- you might also need a blank preset on every bank..Dont understand why you wouldn't want to be able to turn presets off the same way you cut them on? Perfect world (for me) cut a preset off (by pressing the preset) and the pedal is in true bypass- small gripe on an awesome pedal
I mean, what you're describing is basically snapshot mode--the ability to turn multiple things on and off with a single foot switch. The bypass functionality is really only there as a fail safe in case something weird happens.
It really sounds like you should just get an inexpensive loop pedal and put the HXFX in that. Then you can get what you describe without having to use more than 1 footswitch.
