I’m assuming you want to control Preset A and Preset B bypass states within the same Program. For this to work, you’ll have to use an external aux switch and store the Program with one preset active and the other in a bypassed state. Then in Global – Pedal Control, map “A act/byp” and “B act/byp” to the same aux switch. With one press of this aux switch, you can seemingly toggle active states for both presets.
