Ok. So i got the GCX, Ground Control, and the custom cables just came in the mail no less than 30 minutes ago. Only problem i had is the people i got the midi cable from sent me one that was too short. No big, still works, ill get a longer one later. I plug everything in, and the first problem is the ground control. I plugged it in, and it didnt turn on. I thought, ok, maybe i put it in the wrong input. So i put it in Midi Out instead of Pedal In. Still doesnt turn on. I plug it in with 9v power supply, it goes right on. Is it a faulty midi cord? Also, when it was on, and it was showing all the presets that were on it (from the previous owner) and i was pressing a few buttons, i noticed that only 1 went on at a time. Is it gonna be like that when its all working???
