My DL4 has been acting up - whenever I go to save a setting that I have created using a different effect within the DL4, it saves it permanently to whichever switch I assigned it to - A, B, or C - and stay within that switch (A, B, or C) even when I move the model selector to different effects. For example, if I were to make a setting in Reverse mode and save it to bank A, bank A will always play that setting from Reverse mode, even when I change the model selector to say Digital Delay, move to B and back to A, unplug the unit and plug it back in, fiddle with the knobs in a new model selector, etc. Is this how the DL4 is supposed to work? If so how do I make the A, B and C selectors specific to which model selector I am on and not which voice I last saved to one of them? Thanks very much.
