@Budda: I don't use an FC, but it was pretty easy to identify the functions utilizing the Control Switch and changing that to an external controller (e.g. a dedicated midi command) or a momentary switch connected to one of the Pedal switches on the III. I do think some of the presets benefit from jumping from scene to scene rather than only staying on one scene.
And the patches sound have a lot going on in the stereo field, so I would recommend changing your output config to Sum L+R to get al of the sounds in there.
