So I just recently reacquired a DT25 (head this time; had a combo a few years back). When I connect it via midi to my MacBook pro (using the DT Customizer) I can't get it to do what I want. For example, when I am on channel A, Voice 1, when I change the Blackface Double to a Blackface Deluxe Vib on the Customizer, instead of staying on Voice 1 the amp automatically switches over to Voice 3, even if the Customizer is set to Voice 1. I don't ever remember having this problem with my combo when I used the iPhone Customizer app. What am I doing wrong? Is it me or is the Customizer not up to par? Any help would be greatly appreciated!
