With an amp, a floorboard (FBV3), and apps that have such high degrees of complexity, it is astounding that there is not much documentation support here. For an example of how to do it right, and sell more product by the way, look at what Korg does with their synthesizers etc. Very detailed models to get in depth how to kind of information. Surely Line 6, if you are looking at this thread, must have some of the stuff written down?
