GCX wiring and GCPro IA questions

Post by Dday »

Wiring a rig for a friend and have some questions...
Can the GCX be wired to switch between 2 wireless units? He's also using a volume pedal after them, if that helps and/or adds to the mess.
Can the GCPro's IA be used to send program changes on a midi effect (Line 6 Echo Pro)? I was trying to program IA 5, 6, and 7 to pull up specific patches on the EP, but no luck. I'm guessing either pilot error or CC only.

Thanks for the help-
Dday

Switching between two input sources can be done with a single GCX Loop, however you would need to re establish the ground connection on the Return jack by connecting its Sleeve connection to the Sleeve of the adjacent Output jack.
Before you do this I must ask... are these two wireless receivers are there with one simply being an emergency backup? If so, then you would be better off with an external A/B switch for the two wireless receivers.

A Ground Control Pro Instant Access button will send a single Control Change message.

I hope that helps!
