Emergency, GCP is not working :-(

[mhjn]

Hi,
My GCP all of a sudden stopped working. When I press any preset button the Active led on GCX turns on, but it doesnt switch preset. When I'm turning individual loops on and off, the GCX doesnt react

I'm on tour, so I really need to get this fixed...

Thanks,

When powered up, does the Active LED on the GCX remain illuminated and flash on/off when you press any buttons on the Ground Control Pro or does it only flash while otherwise remaining off? Are you controlling anything else in the rack via MIDI? If so, what happens if you power the Ground Control Pro directly and connect to the MIDI In of the next MIDI device in the chain... do your presets work?
