I know with the UNO eprom you can toggle 2 CC's when selecting a patch. The newer stock eproms have some of the uno stuff not sure how much. I used to do this for a lead boost for a while before I went back to a stand alone wha pedal. Now I use the two pedals on the FCB. One controls delay mix the other gain/volume. Just program the initial patch with the two things (CC's)off then hit the same pedal again and they turn on, once more to turn them off. There is no delay. You can program any cc's you wish per patch that way but only two.
