i too have a bad monkey error 80000000A, i bought a very cheep Midi to usb interface , i should say i do not know very much about midi and hope i can get some tips on what it is im doing wrong . i got the drivers for my midi interface and my computer says its working fine , when i plug it into my DT25 it does not see the Version that it is, ive re set the amp by pinching the class and pentode switch together while turning on the amp and with no luck and i also tryed to do the update with the amp in safe mode by holding the channel b switch down while turning on the amp with no success. Is their more than one type of midi to usb interface ? thank you for your time on this matter any help is much appreciated
