Hi, new around here. Boughted a Tempest a couple of years a go, never updated the OS because I never used MIDI way of working etc, now that I am trying to do so, I had problems to update it to the latest 1.4 OS. My one has the original 1.0 and after trying to follow the instructions I can not make it work. I can not find the Global button to change the cable option or either the 1.2 OS that I need to update for the first time my Tempest, so I am very stuck with this and I do not know how or what to do. Any help would be very much appreciated! thanks
