I have a Sansamp Programmable BDDI. Let's say I go to Setting A by pressing the footswitch. I realize that the gain is a bit too high for my taste. When I reset only the Drive knob (and all the others are elsewhere) and doublepress the FS to store the new setting, will I get my old setting with the modification to the Drive knob or will I get the present setting of all knobs?
Unless you unlock the other controls they will remain in their preset position and only the control that you have changed will be stored.
