Jeez, this again? Stagescape M20d's Smart FX was pretty much the exact same thing. This time we simply chose to show an image of the selected model instead of a big, boring empty field:
There are
obviously other screens to look at. IMHO, the signal flow view is the lamest, least helpful, most engineer-brain-centric view in any multieffect. It should only be used when organizing your blocks while first making presets. That might be why I like using HX Effects so much—the signal flow view is hidden in a menu and 90% of the UX is just 1) touch a switch to select, 2) turn knobs.
Once Stadium is shipping, y'all can suggest alternatives for what you want to appear in the Focus view field.
