I do not know how to build any thing like the axe fx(or how the magic is put inside), but I would guess the reason the a,b,c,d, knobs are not set to lets say b,m,t,v of an amp is because what amp would you want it set on? will every one want it on amp 1 or amp 2, will some want it on gain and input? I kinda like the way it is. I use it for mix on effects a lot, but not all presets have the same effects. as far as auto save , please no when some one goes to your rig and says wow is this an axe fx(wile they are turning the knobs) I will settle with save, enter, enter. It would how ever be really nice to have the ability to attach these directly to b,m,t, on a preset basis instead of using the edit alighnment trick we are all so good at.
