I've been using a GCX and Ground Control unit for a couple of years now and for a couple of months in the middle of a show my GCX will stop "listening" to my ground control, all the loop lights will light up continuously and all my effects will be on... until I shut the unit off and turn back on it will be unresponsive to the ground control unit. I've replaced the cable three times now in two months so that's ruled out. I fixed a couple of broken solders on the MIDI input jack on the GCX and it seems to be a little more reliable, but it's still doing it. Anyone had this problem? Any ideas what it could be or how to fix it?

You could make a pedalboard junction box. 7pin XLR going from rack to pedalboard. Much more reliable.

anyone else?

If the MIDI jack had to be re-soldered due to cracked joints then likely the Power jack suffered the same damage. It is also possible that the jacks are simply worn out from continued plugging and unplugging or from the cables being constantly under strain. It certainly is not normal for these jacks to crack the solder joints under normal use.

No, I agree John... it does get beat up pretty bad on the road with 200 dates per year bouncing around in a trailer through crappy Canadian roads! I'll check out the connections on the power supply and possibly replace the input and power supply connectors. thanks for the help!

success! there was still a cold solder on the midi input jack from constantly plugging/unplugging my board. so now that it's fixed I drilled a couple of small holes through the back and into the corners of that jack and countersunk a couple of small screws in there to keep it from ever moving again!
