Got the MC6 (Midi Out) into the Axe Fx (Midi In) with 7 pin midi cable. Screen on MC6 just reads empty on all banks and buttons on MC6 don't do anything when pressed. How do I start saving preset tones from the AXE to the MC6. I'm a noob to the Axe and MC6 so please explain it for a dummy. Both MC6 and Axe firmware is up to date.
