Hey Rich,
You gotten some great help here already. I am just chiming in because I have been a AxeFX user for a while, and the MAJOR thing about the edit programs is the ease of programming. It's simply SO MUCH EASIER to click on a parameter than to scroll through on the unit itself.
Everything can be done on ANY of the units, and of course if you need to make adjustments at a gig, that's what you'd have to do unless you have a laptop with you. I never do, so any changes I need to make at shows is done the "old fashioned way."
However, once you use the edit program, you'll wonder how you lived without it. It's just so simple to use and edits are quick and then can be saved over multiple presets if need be.
You never HAVE to use the edit programs, however if you have a computer it just makes a TON of sense.
Good luck and welcome to the insanity, I mean family, LOL
Thanks, GL. I'll see if my wife's home computer has enough capacity to download AX8-Edit. I would still like to know how to set up one-touch preset switching on the unit itself. I did what was suggested above by the Administrator, and though the changes were saved, I still needed two touched the change presets. Can you give me some instruction on this?
