I use Arturia Keylab MK II midi controller both 61 and 88 keys. In User mode, program change works well with OB-6 when "preset" is activated. I tried "category" button for bank change. On Keylab's screen, bank change is being exsicuted, but OB-6 does not respond to bank change order from Arturia. OB-6 only changes patch numbers in the same bank. What should I do to make OB-6 respond to bank change from Arturia?
